hgnowhg: Hey, you're mistaking something... the SDK is downloadable and build-able back to the version 2.X (well, at least last time I tried I could download and build 3.X versions, and I saw the 2.X tags there too). The SDK (and it's bugs) have very little to do with Flash (Flex) Builder. I'm not trying to defend the SDK or FB... But, consider this: If you have a prior version of SDK - you can always go back to it and build against that version regardless of the IDE you're using. I do most part of my development outside Flash Builder, because I like another IDE better. But I need to work with few other people, who do like FB, so, I'm arranging my projects in a way they are IDE-independent. I can build it from FB, but, if for whatever reason FB is being stubborn and doesn't like my project, I switch to command-line / Ant etc, and then I can build it anyway, so long I have the compiler that can do it. More yet, I'd recommend to do it this way if you want to ensure that the project compiles - do invest some time in organizing the builds, and you're protected against temporary bugs / changes in the IDE. It's really unwise to rely solely on what and how the IDE does while using beta versions of it and / or upgrading.
So, regarding your situation, I'd just go to the SDK download site, grab the version you used with the beta, and would set FB to compile against that version - problem solved. If, for whatever reason FB doesn't like your version of SDK, you can always make it "shut up" by changing the builder in the properties to Ant and compile with flexTask.jar against your chosen SDK version. FB won't even know how / what's being compiled. Best. Oleg
