CODMW2 70 hack

So I downloaded the MW2 rank 70 hack and i followed every single step carefully. When I started up MW2 I pressed easy upgrade and it ranked me up all the way to 70 as expected. I played one game of team deathmatch (people said you should play 1 game to ensure the rank is saved) and after I finished the game I exited MW2. A couple hours later I started up MW2 again and, "Your data is from an old version of the game. You must reset your rank and unlocks to continue." I reinstalled Modern Warfare 2 Multiplayer also and the problem is still happening. SS below PLEASE HELP

**Here is the link of where I downloaded the hack.

I downloaded the 1.068 version because of the MW2 Multiplayer update.

lol, shudnt this b in the MW2 Section???

do u play the pirate version or the legal?
Cuz steam might've updated the game...
try 2 reset, and do the hack again, or find another1, that worx the same....i didnt download yours...but its called EasyAccount? If no...then find EasyAccount - its great!

i have this same problem i have to redo the hack everytime before i re-enter the game it beats have to lvl up there but with your rank goes all your classes if u just leave the game open and dont close out of it and just leave it running 24/7 it will stay but otherwise as soon as u press quit be prepared to re hack it so i just leave it running for a short term solution untill a better one that fixes it is available

wow stupid
