Is this a scam?!?!

[mr_suspekt]

I needed a new Registration Key to my pokertracker and sent a mail to "support@pokertracker.com" and got this back from "pokertracker@gmail.com":

"get this patch
http://www.pokertracker.com/forum/viewtopic.php?t=20594
and send the new product ID."

I didn't see that it was sent from a gmail adress so I downloaded the patch and installed it on my computer. When I was finished I notied the gmail-adress and paniced.

Is this an obvious scam (just seems a bit strange to hack an small/medium stakes grinder?) or am I being paranoid?

Haven't logged into my account yet and won't do so until I get some responses from you saying that it's common practise by the PT staff to reply from a gmail adress.

Thanks!
