Ok Guys i have a fix for garys new update

Fist Create a File called Steam.inf
then type this in there

Code:
PatchVersion=1.0.1.0
ProductName=garrysmod
appID=4000

Now all you have to do is put it in orangebox/garrysmod

If you get Failed After 4 retrys delete your admin mod (Im afraid to say ASSMod Works)
