Some other things to try while you wait for a response to your support request:
1) Clean and polish your CD, and check it for scratches. (A scratch can happen no
matter how careful you are, and can cause weird problems like the one you describe.)
I once had a CD that had a bug squashed on it
2) Download the CW files from Freescale and try loading from there. (If you have the same problem, you've at least eliminated the CD as the culprit...) (This is only practical if you have a broadband connection...)
