Now I've lost my Windows 7 activation... I meant to modify my BIOS with the activation data from my 10.2 BIOS. Apparently, you did not that and just modified the BIOS without my data... What should I do now? Your tool "OEM Certificate & Key Insert win7" doesn't work, it says "License file has been installed", then "Product key has been installed", but then "Windows 7 has not been activated". I tried to launch it from Administrator account, but it still doesn't work.
