Windows 7 VM Download error

I would like to say thanks to anyone who helps me out here.
I just purchased Parallels 5 today along with Windows 7, but the only problem is when Windows 7 tries to run its setup I the the error message, "The unattend answer file contains an invalid product key. Either remove the invalid key or provide a valid product key in the unattend answer file to proceed with Windows installation."

Has anyone had this issues that could help ASAP?

Thanks again!
