Thanks for the response.

I am am going to heed your advice and try one of those programs.

In the end if all I have to do is swap the REG it wouldn't be such a big deal if it happens again....

This is the second time this problem has happened to me on the same computer.

It is a young boy's computer who only plays CD-Rom games for the most part.

Upgrade won't work, and re-install in...
