Migration from Flex 3 to Flex 4 Errors

Hello I migrated my Flex 3 project to FLex 4: I am getting these errors:

Anyone has an idea about fixing this in Flex 4.

Errors like this are usually due to version mismatch issues. So, make sure that all your external libraries are compiled with the same version of the Flex SDK that your main project is.

If you are using frameworks, or other libraries you found on the web you may have to recompile them yourself if the source code is available.
