Thanks for providing some more details. Unfortunately at this time we just don't have enough information to do any kind of bug fix.
If I understand correctly, you think it's just the more recent version of the file. Does it crash like the video shows each time you do the same thing? In other words, is it repeatable using the same data and same steps each time?
If so, can you:
1. Open the version that crashes
2. Use File > Export > .f3d file type.
3. Attach to this post or send to me in PM.
Thanks, if you can do that we can fix a crash. Without this information it's impossible to fix.
Last, I want to remind you of something very important. Please fill out and send in each and every CER you get. In this case, I can't tell much about your crash (or crashes) because you have only sent in 4 CER in the last month, and only one has comments. So I can't use these reports very effectively to diagnose the problem. In the video you show, the last thing you do is cancel the CER. That report might have held the key to your crash, and thus the crashes of many users. It's a really nice thing for you to send them in, so thanks for that.
Please let us know if you can find the version that crashes, I'm looking forward to fixing this crash.
Thanks,
