Black Ops 2 Multiplayer Launch Issue

[Swndlr]

Hey guys, been having trouble launching Black Ops 2 on my PC for so long now and I cant figure out what is causing it to not launch. Ive had no luck in finding any clues as to what is causing this, because it used to work way back when. The game is installed on my 1TB HDD. Ive done everything from verifying game cache to completely reinstalling the game and nothing works. Anyone have any ideas? It only happens with my multiplayer, not zombies or the regular Black Ops 2 file.

if it is just this game that generates this issue, it would most likely be a problem with the game and not your hardware or OS etc, so you might be better off on the games own support forum or maybe steam community, not that we don't want to help, but there might be more people there who can help or have experienced the same issue and found a fix etc.

other things to try:
clean and reinstall graphic card drivers
move the game to C: (some games may actually be a bit finicky about this and crash if its on another drive)
reinstall windows
