The file cannot be opened as it contains languages that are not configured for this installation

Question

Suddenly I can't use the trados. I get the following message The file cannot be opened as it contains languages that are not configured for this installation I have checked and set the languages I work with and have worked with so far. I deactivated Trados and installed it again. The Same error. I checked, I have my 2 languages set. When reinstalling it did not ask me again to add the 5 standard languages. 
 I tried all the solutions found on the internet, without success 
 What can I do to function normally, as before? 
 Thanks in advance!

Have you configured your translation memories both in All language pairs and in a specific language pair? This is the most common mistake leading to such error message. You may configure TMs only in All language pairs OR in a specific language pair, but NEVER in both. Please check that in your Project settings (NOT: File -> Options!)*. 
 * Should you have that also configured via File -> Options change the settings there too, as these will be applied for any new single document translated without creating a project or for any project based on your default project template.

What is the file name extension of the file you are trying to open? If you do not see the file name extension, go to Windows Explorer, select the View menu and click the checkbox "Show file name extensions". Then tell me exactly what the file name extension is.

For PDF or Word Studio will certainly show a language dialog, as the automatic language pair recognition is not possible there. For me it looks like would you either be opening a sdlxliff file (or a xlf file) or just going to the Files view in Studio and opening a file from there. 
 You can set up Studio to suggest you a most used language pair. To do so, go to File -> Options -> Editor -> Languages and chose the language pair you use the most. 
 And again, please give me the exact file name extension of the file you are opening and not seeing the languages dialog.

Looks better now. However, when you already started your translation, you do not need to open the source file again. Just go to projects view, select the project containing the file you started to translate and open this file from the files view WITHIN Studio. 
 As for the different translation memories: are you using Studio 2021 in the most recent version with all updates?

The message in question about different TMs will not appear in Studio 2021, as this small bug has been resolved there. This means it is time to upgrade.

Trados Studio > 1. Trados Studio
