Hi,
I am having a really weird problem: my game compiles as always (I didn't change it for months), but today Flash Player (an old version, I didn't updated it) all of a sudden started giving me an error when compiling the recompiled SWF: the error is in the SWFLoader getClass function, it doesn't find a movieclip in the library, but it doesn't simply returns null as always did, it now causes an error that blocks the execution of the debugger!
Didn't getClass simply return null if the requested resource was not found?!
