Garry's mod crash on startup!

Help, whenever i try to launch Garry’s mod it crashes without an error. It does though put a crash report in C:\Program Files (x86)\Steam\steamapps\common\GarrysMod (https://mega.co.nz/#!HxVzQZCC!1hZ6gMJvXC8moyJzxQtRoi60DafU1cnV_g9y39EW4ac) <---- Crash dump. However i have located the issue to be in C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\bin and with “client.dll”. I’ve tried to re-download, and verify game cache, but to no avail. I have uninstalled all of my addons so that’s not a problem.
