I had a level 39 marauder, logged back on and it was gone.

I have no idea what happened to my character..
his name was "DESEKRATER", he was a Marauder..
I try creating the same character with the same name and class, then it says a character with that name already exists.. wtf... i am seriously lost..
I even have screen shots of the character.. i have a very complex password so i dont think i could of been hacked or anything like that..
someone please help me out, no idea what happened at all.
I also had a level 3 templar, named "DEMISEOFSANITY" that i played just to try it out..

Check whether you logged in as a different account; this is very easy to do if you are using Steam.

Otherwise, email support.
