[SOLVED] Can't get my lvl changed

So, I have a problem. I lvl-hacked with PSE and EAM to prestige 10 lvl 70, and want to get it back to prestige 7. But on one or another way, it just doesn't seem to work...
I also have a trainer, dunno the name anymore, and that one includes lvl-hack too. When I click on the Prestige 7 button on that trainer, the prestige changes to 7 (as it should.). But after playing a few matches and quiting the game, and then another time restarting it, it's back to prestige 10 again...
So dunno, can you guys help me out?

uuhm reset your stats whit eam
than you play a game.

make a prestige 7 thingy whit pse.
and import it whit eam

that works i think
