hi, windows 98 was deleted off my computer, kids tried loading a game and they ran out of disk space, they started deleting things and got to the windows program. as soon as the computer is turned on a message comes up about missin 98 files it then goes to the windows 98 setup wizard, i can get throgh te first couple of questions untill it asks for the product key. i enter it and it always comes back invalid, then suts the computer down. this is the same product key that i installed awhile back and it worked then. ive entered it a few times to make sure i didnt get it wrong, same results. at staples the told me to try a different 98 product key and it should work, will it
