Retrofit does not do the job on large files + Object reference not set to an instance of an object.

Question

Hello, 
 I am a big fan of the retrofit function. It works like a charm on small files e.g. < 1500 words. 
 But with bigger files (I am currently working on files > 5.000 words) it does not work : 
 I either get the message "Object reference not set to an instance of an object" and then can not move forward with the job 
 or if I manage to get the process of retrofit running by changing the tolerance i get the target text modified by the source text ( in the target there is a mix of the source and of the target but not my modifications). 
 
 Any ideas of what could be the problem(s) ? 
 I work with Studio 2017, SR 1. Thanks

Hi Manuella Lange 
 The object reference error title is very generic so we can't tell much from that, but if you save the error stack to your desktop and then add it to your post then we will have a bit more to go on. It would also be helpful to have your project if possible so we can reproduce the issue? So we'd need the Project and the file you edited for bringing back in. To post the error stack do this:

Hi Manuella Lange , 
 
Can you make them available to me via email? pfilkin@sdl.com

Hi Manuella Lange , 
 
This is just the sdlproj file which is a file containing metadata for the project. I'd need to whole project. So go up a level and zip the contents of the folder. That should contain the source file, the sdlxliff files etc.
