Please let me know if you're able to get it open at all.
Here's the full story. Shortly after I saved after doing a custom classic motion tween, i tried to copy and paste a keyframe, something I do all the time, but it crashed abruptly. I think there is something to the custom tween that has destroyed this file's ability to open. When I launch it, one of my processor cores ramps up to 100% and stays that way forever (seemingly) I've had Flash go from (not responding) state to working before so I'm kind of just waiting to see if it will work itself out but I'm not optimistic.
Did I mention the deadline is in 7 hours? (I lost 12 hours of work)
