I just got windows 8.1 for my computer, and I haven't touched GMod since my previous OS (Windows 7), which was like 2 months ago, where I could run GMod no problem. Now I get this error: http://prntscr.com/8nibui And get re-directed to Microsofts website informing me to download Windows 10: http://prntscr.com/8nic14 I've tried to Google it, but all I get are responses leading me to that link pretty much. I don't care about Windows 10, and I don't plan on getting it anytime soon. I just wanna play GMod without having to update to another shitty windows OS. help pls.
