Problem with player achievements

[Scooby 7]

From the start.

When i played without xfire my character was goin forward with achievements, golden weapons etc. but i decided to install xfire.

Playing with xfire was the same. Everything was good, but I noticed, when im opening CoD without xfire, my character is in the same place where it was before i installed xfire. i tried to copy my folder, changing stuffs a bit etc, but nothing helped.

There is a way so i can play with all my unlocks etc. without xfire?
