It has happened about 3 times now and I don't want it to happen again. What's happening is that my Fla will get corrupted every time my fla size will reach 1.5MBs. And it always damages my fla. The first time, it deleted most of my movieclips in my library, and duplicated the scenes about 4 times. The second time it completely cleared the whole of my scene 1 which was about 500 frames. But I don't want it to happen again since my fla is near 1.5MB again, any suggestions?

Try reinstalling it. I have no other idea on how to help you.

CS5 was the worst C.S they ever released. I dont know what to tell you. Just get Flash 8 or something.

ever tried using a hardrive? im guessing its because of the space in your PC......plus putting your animations in a hardrive will prevent it from corrupting :) but yes, alien is correct....CS5 cant be trusted i know that cus ive been there >:T

oh ok then, ill just convert my CS5 fla into flash 8 then. Thanks guys

wait you can do that? o.O hmmm i should do that to my old anims!
