I bought my Medion PC about a year ago and it came with Vista preinstalled. Yesterday when i turned it on i was shown the above error message on a black background, with three options - 1. Access your computer with reduced functionality 2. Enter different product key 3. Contact Medion AG to help resolve this problem.
These are my only options, i have no access to deskstop, or start key etc. I have reentered my product key numerous times and also reentered a new product key given to me by microsoft customer support on the telephone but neither was accepted and i received the following error message with both product keys: Code 0xc004f050 . The people on the microsoft customer support number could not help me any more and refered me to Medion, who referred me back to microsoft!
I have not performed any updates to Vista or uninstalled any drivers etc.
Any help would be greatly appreciated as i have an important deadline looming,
thanks very much,
