Hello, I have run into this problem once before but I don't remember how I solved it.
I am working on a project and suddenly when I publish everything goes wrong it's like some classes are missing and i'm getting errors I didn't get before.
So I go back to an older version check the previously published swf to make sure this one is not giving errors. And before I make any changes if I publish this file that was working before it also goes wrong. And all other previous versions too even though they worked perfectly the last time I used them.
I think reinstalling flash might be the solution but I was wondering if anyone else has come accross this problem
