Error message when I open a file in Editor: Object reference not set to an instance of an object

Question

Hi, 
 I bought Trados a month ago and started getting this error message (Object reference not set to an instance of an object) when I open a file in Editor, after I'm prompted to choose Source and Target languages and TMs, this message pops up in Editor. It seems to disable TMs and MT. 
 I've tried to uninstall Trados and install it again. That didn't help. I've also tried the Repair button but that didn't help either. 
 Could you please help me fix this? 
 Please find the error details below: 
 Type System.NullReferenceException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 
 HelpLink: 
 Source Sdl.TranslationStudio.Editor 
 HResult: -2147467261 
 I use Windows 10, Microsoft Office Home and Student 2019, it is a Word file, language pair English>Czech, I've selected English>Czech 
 Yesterday I translated the very same file no problem and today when I open it I get this error. It happens with other Word files, PPTs and with .txt files.

Hello Mira Dornakova , 
 Just to close off this thread now support have resolved the problem and so other users know how to resolve similar issues- 
 Support- 
 "Thank you for the time spent in the remote session. W e fixed the issue you encountered by performing a Studio reset and repair, and also added AV exclusions for Studio. . I will now go ahead and close this Support Case. If you encounter any other issues in the future, do not hesitate to contact us" 
 Resetting Studio and adding the software to the AV white list resolves many unexplained issues.

 .If you create your own test project, does the problem still occur- or is it only with a particular set of files from a client? 
 How did you receive the files? Individually or via an SDLPPX (package)? 
 The more information you can provide, the easier it is to identify the problem-

Mira Dornakova said: I saved the error stack clicking on the floppy disk icon, but when I try to copy and paste it here it automatically flags the post as spam and erases it. I approved the post so you can see it above. But if you save the error stack as the error file you get when you click on the disk symbol, and then attach the xml file you get this instead... no errors from the forum and the post is more readable and less messy: Fullscreen 6562.errors_4_community.xml Download Object reference not set to an instance of an object.

Hello Mira Dornakova . 
 I would suggest resetting Studio (and ensuring Studio and MultiTerm is added you your AV) 
 Please take a look at the following Wiki (ensuring everything is up to date) 
 https://community.sdl.com/product-groups/translationproductivity/w/customer-experience/3392/how-to-part-1-trouble-shoot-unexplained-errors-and-unwanted-behaviour-in-studio-multiterm Part 1+2 
 Then use the following app to reset Studio- 
 https://appstore.sdl.com/language/app/sdl-freshstart/876/ 
 If this still has not resolved the issue, you might need to do a fresh installation. 
 First remove the following folders ( Back up all your resources such as TM's and TB's first! ) 
 c:\ProgramData\Package Cache\SDL\SDLTradosStudio2019\ c:\Program Files (x86)\SDL\SDL Trados Studio\Studio15\ c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15\ c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15.0.0.0\ c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15\ c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\15.0.0.0\ c:\Users\[USERNAME]\Documents\Studio 2019\Project Templates\ c:\Users\[USERNAME]\Documents\Studio 2019\Projects\projects.xml 
 Then reinstall Studio (making sure you have admin rights). 
 Please let me know if this has now resolved the problem.

 Can you update your Studio, and probably Multiterm as well? The one you are running is out of date. This may solve the problem, but if it doesn't at least we can start from the point of view of you being up to date. Latest versions are these: 
 SDL Trados Studio 2019 SR2 - 15.2.4.1693 
 SDL MultiTerm 2019 - 15.0.4.56053

 ok - one last try perhaps. Delete this file and restart Studio: 
 c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15.0.0.0\TranslationMemoryRepository.xml 
 If that doen't help I'd recommend you log a case with the support team. 
 For licensing or installation issues that prevent you from working we have a route for all customers to get help. This can be achieved really quickly using this link: 
 gateway.sdl.com/liveagentlicensing 
 You have two options: 
 1. Submit a case using a webform 2. Use live chat to get a licence reset 
 You want to use the first option and make sure that you refer to this thread so the teams can see what you have tried already.
