I am brand new to Mac and Flash. Here is the issue I am having. I bought a
couple of flash templates to build a website with. I started occasionally
having problems with one of the .fla files causing "an unexpected error" and
closing Flash CS3. Now I cannot open the .fla at all. I can open it on
another computer, however. I can open different .fla files, not just the one I
need to.

So I uninstalled and re-installed Flash CS3 but it is still doing the same
thing. There has to be something "stuck" somewhere that's causing this.

Thanks in advance!
