    Difficulty importing Flex 2 project into Flash Builder 4


      I have imported a Flex 2 project into Flash Builder 4 that gives me the error:  "Unable to locate specified base class 'mx.core.Application' for component class 'ExPetition'." when I try to Build it.  ExPetition is the name of the project.


      I can't figure out why this is happening because I imported two other Flex 2 projects into Flash Builder just fine.  I was using ColdFusion 8 with Flex 2 before I got my new computer and I am using ColdFusion 9 with Flash Builder 4 now.  But I changed the Flex Compiler and Flex Server settings for all three projects after importing them.  For two of them I was able to Build Project and run them and they worked fine.  So why am I getting this error importing this other project?  Can anyone help?
