Download the WinXP EXE Fix
Download it onto your computer and double-click on it. When it asks you "do you want to add this info to the registry?" tell it Yes.
If your problem is what I hope it is, it should fix it right away. You can try your programs after using it, but you may have to restart the computer before it works.
In addition, look at the 8 recovery CDs you told me you had earlier. They should have titles on them, such as Application CD, Resource CD, etc. (depending on the brand of computer). Try to find one that says Operating System or Windows XP, something to that effect. If this doesn't work, we can try to use that CD to do a repair of Windows, rather than a full reinstall where you lose everything.
