There's no account named "Gasoline14" when I look it up, so chances are it has been deleted off the server.
It is true that inactivity can do things to accounts, but even more so if they do not go through activation correctly. I know that we had to clean out old non activated forum accounts before we made the move, and if your account was one of them it will more than likely not come back or can be recovered.
There's been this problem(most likely due to the old registration system) that let users go in game and play sometimes even though they never activated their account properly, this more often than not lead to the accounts being wiped from the server, by the server. Wouldn't be surprising if this is what happened, or that your account was one of those listed as pending activation, which would mean it would get deleted in due time no matter what.
There's not much that can be done about your account I'm afraid, as it most likely belongs to the "internet void" now.
