I have upgraded to the latest version of Virtual Box. I can create my VM's but can't load the OS's. I get the following error msg.

failed to open a session for the virtual machine xxxx
The VMMRC.rc module version does not match VBoxVMM.dll/so/dylib. Re-install if you are a user.
Developers should make sure the build is complete or try with a clean build.

I am running Windows 7 Professional.
