Can you share the file so we can try reproducing the problem?
If it's a huge file it could be a memory issue (I'd recommend watching task manager to see if this might the case).
I have uploaded the file here: http://jump.fm/MPKNC
I don't think it's a size issue... the only thing I can think of is that I don't have Illustrator installed on the same computer as Flash so maybe that's causing the problem..??
Let me know.. thanks!
I can reproduce the crash. It's seems to be related to Importing all layers to Stage, and selecting the "Place objects at original position" option. All other combinations seem to not crash, so at least it helps isolate what's happening and provides an option for you to import your artwork and continue with your site. I will file a bug and send this to the correct folks for evaluation - I'm not too sure what the conflict is between the AI file and Flash (it's not due to not having AI installed).
Thanks for posting it!
I got it to work now by doing what you said... thanks!
