I know I’ve read a few other posts about this but I’m not really sure what the problem is or what I’m supposed to do. Basically I have a very large project with lots of classes and it sounds like I’m going to have to go in a rename a lot of stuff. When I publish my movie, just about every class, including all the ones in the library give me the “variable classname is not defined”. How do I know what is causing the problem and how do I go about fixing it? This is going to be one gigantic pain if I have to go in and rename hundreds of references. In fact I might just go back to CS3 if that’s the case.
