checking the license - Error

[Ken]

I was restoring my computer when it crashed. We I
rebooted I get "A problem is preventing Windows from
accurately checking the license for this computer. Error
Code:0x8007007f.

Any help would be greatly appreciated.

Thank you!

If it's not booting then you'll have to do a repair
install if you have a xp cd. If you have a OEM restore cd
then it's a clean install and you will lose everything on
the drive. I would do a repair in case you're missing more
than you think.

If it will boot this will do , have your key ready:
