Its a Gateway machine, used the Mega Gateway bios to flash, did the cert and key, was great. Runing SLIC Toolkit, it comes up with ACRSYSACRPRDCT_V2.1. Last night, it came up that my Build 7601 is not genuine, I had used Win 7 Ultimate 32-bit for my install, and things had been working fine until then. About 3 to 4 months. I have tried different Certs and keys to no effect. Ran OpaTool and same result. I'm at a loss, any ideas?
