Internal Application Error message in memoQ

Does anybody know what this message means? This is what we did, we imported the file, pre-translated the document, locked specific segments, and then export bilingual file. As we were trying to export the bilingual file, we got this "internal error."

Thanks in advance to anyone who can help!

Sorry about it, this is a bug related to memoQ's versioning feature. This might appear if you enabled versioning on the first page of the new project wizard. Can you help us tracking this down by writing to support? We'd need a snapshot of your project which is normally under My Documents / My memoQ Projects / project name.

Thank you!
