I have all the Half lifes all the way to episode 2 and when i try to mount it on to Garry's Mod it has a subtraction sign next to the folder and I cant mount it i cant see any of the textures or anything without please help.

Try to play each one first so they convert to Steampipe. Though I'm not sure if all of the episodes work on Steampipe yet.
