I didn't do anything to get this error!
It was a normail day,, I sat in my chair and thought "MAPPING TIME! :D", so I opened hammer and got this: omg lol nub wtf?
What's this?
Also, if I try making a new map or open an old map, it says "Material: Hammer gird" could not be found (or something like that).
I've tried to do the following things to fix the problem:
*Refresh SDK content
*Refresh and delete local content
*Manually delete both sourceSDK and SourceSDK_content files in steam user folder
Nothing works.
Please don't tell me to reinstal steam, cuz it sucks!
Thanks!
