Activation Key

[Pᴀᴛʀᴏᴋʟᴏsᵀᴹ]

Hey Admins,

I didn't really know where to post this because it's quite unusual and hope here it's ok for you :S as you may know I've been playing NordInvasion for quite a lot of time now and my accounts are connected to a certain activation-key. But this activation-key actually is the one ofa friend which doesn't run over steam and I bought my own one on steam about a month after I started playing NordInvasion but continued playing with the old activation-key to not loose everything. To the fact that the new activation-key is connected to some other mods I'm playing and runs over steam my question is if it is possible to transfer all my NI accounts to my new activation-key.?

Thanks in advance
Patroklos
