My only comment is that tarring someone based on the language they use really seems a bit much. Reach conclusions based on the other factors if you will, but throwing in the equivalent of 'boy, you don't sound like you're from around here,' is kinda gratituitous IMO - profile away.

 Kaihean, I don't know what they would say but it can't hurt to email or call Smith Micro with the serial number & if possible the name of the former owner and explain the situation.  Maybe they'll cut you a deal or maybe they'll tell you to p___ up a rope - nothing ventured, nothing gained :-)
