Weird Error

i get this weird error when i start mw2

any idea on how to fix it ? /

Are you using aIW? Reinstall aIW. If not reinstall the game, or verify integrity of game cache in steam. (search on google)

yes im using aiw
the problem is that the aiw website is also down
which is why i cant reinstall aiw :|

It's not down, keep trying.
