Hey friends,

I have SDL Trados 2015. I edited, saved and even exported the files for bilingual review, but now can't open any of the files of the project nor finalize them. I have pasted the details of the "Object reference not set..." error message below. I suspect an issue with comments but it's just a hunch. Can anyone help me? BTW I worked on editing these files all day and didn't use a TM when committing the segments.

Thank you!

Details of the error message (one file):
