Flex SDK policy is that it is ok to make changes to class signatures in order to fix bugs and provide new features. The only cross-versioning support we have is known as the Marshall Plan. You can read about on the open source site.
I think your problem may be compiler version or RSL mismatch. Do you only have one SWF? Does this error happen at startup?

I never had this problem when changing the SDK version before. Its kind of hard to make sure all the 3rd party SWC are updated to the specific SDK version ... Regards, Dima Gutzeit.

All SWCs must be on the same version and must match the compiler version. If you are using RSLs, the RSLs must be the correct version. CSS SWFs and Resource Modules have the same restriction. The console should show that SWFs are being loaded.

When I try use any SDK version higher than that (3.4.0.9271, 3.4.1.10084) the project compiles but fails with the following when I try to run it: VerifyError: Error #1053: Illegal override of FlexModuleFactory in mx.core.FlexModuleFactory at global$init() It very frustrating ... Does anyone has any clue ? Thanks in advance. Regards, Dima Gutzeit. P.S. - I am not loading any modules in my project.
