THIS ISSUE HAS BEEN RESOLVED AND IS BEING LEFT OPEN IF ANYONE ELSE RUNS INTO THE SAME PROBLEM. THE SOLUTION FOR ME (Clambakin) WAS TO UNINSTALL STEAM AND REINSTALL IT. IF YOUR PROBLEM IS DIFFERENT THAN THE ONE BELOW I RECOMMEND MAKING A NEW THREAD FOR YOURSELF. The error says this Engine Error Steam Error: No SteamHTTP. Make sure that Steam is up to date. Try restarting your PC. Try Garry's mod -> Delete Local Content Please let me know if you solve this bug! Here's a picture of the error message. View attachment 818 My GMOD just randomly stopped working today. It starts to load and then cuts out at blue screen. I have done everything that the error message suggested above. I have done all of those things and then I have done even more: Varified integrity of GMOD, HL2, and CS:S Deleted and reinstalled HL2 and CS:S Quitting Steam and loading it back up. Logging out and logging back into Steam. Made sure HL2 and CS:S are up to date. None of this has solved my issue. Please help me! I really need to get back on GMOD considering I'm an admin. Thank you.
