Redownload the games. They have things written in the Registry which will be gone with the new install. If you have saved games which you'd like to keep, either find out how to transfer the savings to another installation, or install the drive as a secondary, reinstall the games to the secondary drive over the existing ones (for new Registry entries) and hope that the settings haven't changed.
You'd get the best results by reinstalling everything, possibly being able to transfer the saved achievements.
BTW for a non-English co-AH'er your spelling is very hard to understand, but if you don't like to get answers from others than illiterate natives it's OK. I guess...
