Invalid Weird suspension o.O

It was a perfectly normal trade, i wanted the scottsmans skull Cutter and the half zatoichi, so i used TF2WH to get it and when i wanted to see what i would get for selling some stuff (Salty Dog,Genuine Snipers Shako, 1 ref, and the haunted dead little buddy) it just suddenly shut down, i tried it again and when it got on it said i had been suspended. I do not know how, i have never stolen anything (i dont even know how ._.) and im not quite sure why i was suspended. please help me.
