Busykid508: Done a clean install of Windows 7 Ultimate today and after that I upgraded the BIOS with the modded BIOS you had produced and everything just works fine. The install of the Acer Cert and the Acer License Key was just a peace of cake and everything works great now. Even used WET to copy back all Data and partly the programs without any problem. Thanks a lot for the great job you had done for me.
