Cyber Max

Hi, I use to have an account on Cyber Nations and last played 12 mouth ago and now when i tried to re-register it says im banned from the game. I did'nt break any rules or register muilty-accounts and to the best of my knowledge did not get banned. Why cant I re-registyer or even recover my older account. If im really banned then I politely ask for a explanation as to why. I'll appreciate any info or explanation and sorry if I used up your time.
