You want to know something really sad. I purchased my copy years ago as well. It was brushed off to the side for another title that grabbed my attention at the time (cannot recall which one), and then it got neglected for another... and another... etc.
In fact, to this day, I have done nothing but install the game I paid for sometime ago. Therefore, I would have clearly been better off just vying for the day it would become freeware...
Sad, but true.
P.S. Now I have Metallica stuck in my head.
Here is a hug for you bro. There there.
