I do computer tech for a small university. I have a students XP Pro laptop which we had to run repair on (we provide free computer repair to all students) and as part of the repair it naturally asks for our XP Pro volume licensing key. The key was entered and accepted, then the install locked up with the ubiquidous 39 minutes remaining (sat there for over an hour, no HDD activity). I did a hard reboot and restarted the repair, but now when it comes to the activation key window, it says the key (same one as before) is not a valid key. Where do I go from here, is there no way to get past this roadblock? We have 3 or 4 VLK's all of which work ordinarily, but not this time.
