Animate crashes on open

I’m using OSX 10.5.6. Animate was working fine earlier, but then it started crashing every time I try to open it, just a fraction of a second after I double-click on the app icon. Rebooting the machine didn’t help. I guess I’ll probably need to reinstall, but I’m concerned that this may continue to be a problem later.

There can be many reasons for this.

What has changed recently on that machine, new software, new hardware? Do you have enough space on your disk? Are you on the same account? Is the license still installed? Did you try other icons, in the Applications folder, in usa.bundle’s package?
Do other programs works fine?
You can try to reinstall since it’s quick to try.
Which version, PLE or full?
Did you change a setting, or some other program, for the display (like resolution, color depth, antialiasing)?
