Successfully slipstreamed SP2 and my original WinXP CD, but now the Windows XP software key on my original WinXP CD doesn't work anymore - when I try to install from the new CD, I always get the error message, that I've entered the wrong key. Any ideas what the problem might be??

Thanks much in advance

Are you sure you used the correct CD? I own an update and a full version CD of XP. Once a long time ago I attempted to do a "clean install" of XP on my system and it wouldn't accept my "upgrade" key. I realized that I had used the full version CD by accident so I had to install it all over again with the "upgrade" CD so it would accept my "upgrade" CD. Hope this helps, if not let us know and hopefully someone else will be able to add more to this and have a resolution for your situation.
