[SOLVED] MW2 Rank saving?

I play MW2 on 2 PC systems (1 at home, 1 at work) and for the life of me I cannot get them to show the same rank when I'm playing.

Ex: last night I was playing at home at rank 52, on my way to 70. I show up at the office to play and I'm 45.

*Note: I did use EAM before to run 70 10p and I had to reset everything and relevel legit to 52.

Are the Multiplayer ranks not synced somewhere so you can play on more than 1 system?

So now I'm sitting at rank 1 at work after resetting everything, hoping it would pick up my real rank of 52 like I have at home.

well you should look at these folders:
steamfolder/userdata/some random numbers(even more than 5) and then copy all of those .bak things on an usb stick
and then drag your files in your other pc in the same folder and if it says to replace some other files you should press ok

i think thats the better way to do this
i m not sure if its workin
