damn error messages

i was playing on a server the other day and noticed several error messages, figured that it was just an issue with counterstrike or something, so i reinstalled cs:s, then i tried to play again and i still got error messages, and now i was missing tf2, ep 2, ect. frustrated, i redownloaded episode 2 and tf2 but none of the models will load. what am i doing wrong oh magical forum gurus?

You aren’t really clear about what server. A server you played on before?
Errors in text (top right) or just Errors “inside the game”?
