Flash CS4 not working

It just started today.

At first my masks wouldn’t work right, they would show if I scrubbed the play head but if I ‘tested a movie’, they wouldn’t show. Then my classic tweens wouldn’t move right.

Eventually the whole program became very slow, when I did a ‘test movie’ it was just a blank white screen, and the pull down menus are all greyed out and unavailable.


I’m running on OSX 10.5.7, and have already tried rebooting the computer. The only thing I did recently to the suite was change the color space setting, but I don’t think that would do anything to Flash.

Any ideas?
