Issue publishing French SL3

I have an English and French (Canada) version of a SL3 project and for the life of me I can't get the French to publish.  I keep getting an "unknown error" message. I didn't create this project but am cleaning it up etc.  There is a question bank in it and I'm wondering if there is something there that's causing the problem.  I opened this window up and I have no idea what to do with it if anything?
