I had assumed this his failed attempt to use "the number in userdata" (Steam3) would mean it was something other than Steam3. That's why I suggested something else.. But looks like OP was wrong in the first place. I keep saying assumptions make mistakes, yet I fall into this trap when the OP gives wrong info. Of course, I'm now making the assumption that you're correct, Asher.
Well, keep trying, Benoist!
