Poker Tracker problem

[BoerfSt]

I'm at work and have only a few minutes time to do this so plz dont flame if this is not the place to post this.

I formated my pc.I saved every .mdb files in the pokertracker folder+ my full tilt handhistory folder. After the format I putted these files back in place. When I start PT and import my hands it only imports 20k hands of 25nl and says i'm a loser at 5bb/100 hands.I have 40k hands in total on 10nl and 25nl at 4bb/100..
First I thought it was becaus I didnt had Office installed and it couldnt read my .mdb files.But after I installed Office nothing changed..

Again, if I'm not in the right place to ask this plz just say it.I'm at work and if I dont get any respons, np, I will look on the PT site when I have the time. But in the meanwhile I ask here.
Thank you
