How To Use Source Sdk

Same with me. Part 1: Cant you use GtkRadiant to edit 'Half Life?' Part 2: I have the same problem. I also cant use mods like Garry's mod, Death match pro (For HL?DM),Exile and other ones.

Cleanly Reinstalling Steam

I bought Half Life? (DVD) but it wont appear in steam. I have CS:S, Half Life? Deathmatch (That I dont play, I play the HL?DM I got from one of steams events 29.7 hr's of pure multiplayer for he last 2 weeks and they just started.) and HL:S They all came with HL? DVD and they work fine but they dont showup in steam!.About HL?DM, I dont play the oreginal game cuz it doesnt find any server.

Same with all the MP modes in those games. One last thing.
