So I was playing HL2 without problems (besides some long load times) yesterday and now if I want to play any game in my Steam Library I'm getting a quick "Validating Steam Files" message and it jumps up to 100% in a second. I try to validate under properties too, but this validates the game not "Steam Files" and causes about the same effect. It validates up to 20 or so % before jumping to 100%. (Auto validate jumps from 0-100). So far I've tried restartingand deleting, and re-downloading the game files. Nothing seems to be working. Should I just remove everything Steam Related and redownload everything(would like to save my HL2 Svaed game), or what? Sometimes I also get the servers too busy message too. One more thing, I can't play any installed games offline(HL2, Portal. Is this normal? It just tells me it needs to be online to play and then it jumps straight to the validating window.
