This is usually happening when you are returning back to Special Edition license.
C++ support is not included in special edition.
Did you use a temporary license? Perhaps the temporary license has expired.
If this does not help, I would suggest you to submit a service request at http://www.freescale.com/webapp/sps/site/homepage.jsp?nodeId=054670.
Make sure to attach the license file you are currently using and specify where you installed the license file.
