Animate program stopped responding after attempt to tween

[Derek Draws]

I just attempted to use the tween feature and immediately the program froze and quit responding. I don't want to lose my work but how do I stop and also prevent this from happening in the future?

save your project with different names.  eg, if you start a fla with name adobe.fla immediately save as adobe_v000.fla.  make whatever changes (no more than 1/2 hr worth of work, for example), then save as adobe_v001.fla.  etc.

then if you corrupt a version, you can return to the previous version having lost, at most, 1/2 hr worth of work.  pick a save frequency that works for you.
