Re: Very odd windows licence problem ?
I'm afraid your best bet is to phone Microsoft.
Are you doing a restore or a re-install?
If you are re-installing even on the same laptop that it was already installed on your key won't work, OEM keys are 1 shot only, technically you should be able to use it on the same machine but for some reason when doing a new install It thinks your key has already been used.
Phone MS they should be able to help you.
He who has never failed has never attempted anything worth succeeding at.
