I work on graphic files all the time and several times a year I like to format and partition my hard drive and reinstall all of my software so I have a clean drive. After doing this several times Win Pro XP will not let me use the key number that came with the software when I purchased it. I have had to call Microsoft for a new key number the last 2 times I reinstalled Windows. Is there any way around this? I have also had to replace the hard drive and ran into the same problem when I installed the software. TIA Debbie
