|Hello again. Wasn't that one of the problems you were having before?|
No, there's no time limit or number of uses for a product key. OEM and retail keys are different but other than that any 98 key works with any 98 cd. So are you sure you used that key previously with that same cd?
The only time I had that problem (and knew the key was right) was when the hard drive failed during installation. Apparently the formula to check the key I entered was supposed to be written to the hard drive. Then when I entered the key it couldn't find the formula and gave me a wrong key error.
Maybe it could also happen if the hard drive had some bad spots or the ram was bad.
