well i've tried everything i can think of, but nothing seems to be working. and i figured this would be the best place to come for help here's my problem, generally i can't use any of the tools. the issue varies by what game I'm trying to use. some games say that they are missing all of their configuration information with the tools, others give me fatal flaws, for instance half-life 2 with face poser gives the error "Unable to load manifest file 'scripts/game_sounds_manifest.text' " and with hammer editor when i load or create a map it says "failed to load the default scheme file" I never had these problems before and i think it's the 2013 update that screwed everything up. I've reset the game configurations, refreshed SDK content, verified the integrity of the cache for the SDK. uninstalled and re-installed. verified the integrity of the game cache, but still nothings working. anyone got any ideas?
