i just got tf2 & i thought i'd have a blast playing it. but when i tried to play it, all it did was close and say it was experiencing an inconvienence and needed to close. i asked a friend of mine & he said i was missing the materials folder. he gave me a materials folder & i tried again. it still doesnt work. after the update i could connect to a server w/ less than 2 people in it but it would be a rainbow of colors & would be really laggy. what should i do about this? my video card is just fine for the game but i have no clue what else i should try. any help is greatly appreciated.
