I've heard three different fixes as this isn't a new error.

1. Add boot.exe to the DEP
2. Check compatibilities settings on your shortcut and make sure it matches your OS version. Many people had it stuck at winxp instead of win7.
3. Uninstall, delete the folder in program files, delete the folder in my documents, reinstall. Backup anything you want to save from the my documents folder. You can actually backup the folder in program files and restore it after its installed so you don't have to redownload everything.
