v33 texture problem

[Roachy]

There is a much faster way considering you already own HL2 EP1+2, all you have to do is right click on the games you wish you mount. Go to properties and click betas, opt into the SteamPipe beta then run the game. It will say it's converting the new files. (It's being added to SteamPipe for capabilities with GM13) then when you run garrysmod, make sure they are mounted and you're done. I had the same issue and stumbled across a nice little post on Google, worked for me and around 20 other people.
Happy to help
