有steam的玩家這樣做便可以玩了:
my issue seems to be resolved. Played for about 30 minutes without any probs. I opened Steam, went to my games tab, right clicked on Left 4 Dead and went to properties. In properties I clicked on the local files tab and then clicked on "verify integrity of game cache". After it was done Steam gave a message that Left 4 Dead had finished downloading (it didnt download). I then closed that window, went back to my games tab and right clicked on Left 4 Dead and clicked "Launch Game" (instead of using the shortcut on my desktop) and everything worked fine.
