I own small business. Today this error code came up. My local tech guy coming tomorrow but says he has never seen this. I have done some research about it at home tonite- can’t get into computer at office- and have seen the question mentioned but no answers. Help!!? Machine has worked well for 3 years until this. Windows XP, I believe Home edition but did not check before coming home tonite. message says; Preventing Windows from checking license. Machine from reputable dealer- believe it is Gateway.
