The old projects from FB4 imported classes from the Flex 4 sdk and your Flex 3 compiler is complaining about classes that it can't find in Flex 3.
If you want to compile against Flex 4 in FB3, then set up your SDKs to add the Flex 4 SDK, and point your project(s) at that SDK instead of the default Flex 3 SDK.
If you're just building Flex3 code (and your projects that you imported aren't using and Flex 4-isms), then do a clean on those projects and rebuild.
Chet.

Subject: [flexcoders] Matrix3D error
All,
I just installed FB 3 and now my imported projects done in FB 4 beta 2 give me this error
"Type was not found or was not a compile-time constant: Matrix3D."
How do I get rid of this?
Thanks
