Almost everytime i connect to a server, the game dies, "Hl2.exe has encountered an error," blah blah, can you give me any suggestions?

a) say exactly what the error says.
b) do you have source sdk base installed - if you dont you need it installed and if you got your games from a free steam package you need to buy a source game on that account to have sf working.
c) verify the integrity of your gcf files from steam right click on your games in the steam games menu and properties > local files [verify integrity of game cache]

Ya, i have sdk base

use windows search, find the file. If it's in the steam folder or a subfolder of it, shutdown steam, kill the file, restart steam, recheck game integrity of source sdk and hl2dm and retry please.
