Yeah, in fact it is a protection. This the log of the program, it is small: fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the registry for bias 180, std (d/m/y): 15/02/2009, dlt (d/m/y): 18/10/2009 fixme:reg:GetNativeSystemInfo (0x4dc28f) using GetSystemInfo() The name of the application is sXe-Injected. It is so controversial for me, they make a server version especially for Linux, and the client version they don't let you even emulate. It's so sad I still can't find a way to use it. This program makes the Counter Striker I have installed in my PC obsolete.
