You should check aCis forum for the fix, you can find there even 2 ways how to fix it. If you can't on your own.. :D
Because they don't know how to fix things, that's why they "don't give a shit" :P
From where those guys come from.. No clue and want to open a server.. If you really want to be an admin/gm, pay someone for the pack, to create it for you. At least it's gonna be "normal".
To be honest, it's not. You can say that your bro or a friend of your used your account without permission. You wasn't present in that time. Who knows, it's worth to try.
Yeah, but if your server is not added yet (validation period 1-3 days?), then you couldn't configure it until accepted. But as you said, most likely it's provided @ "my home" , then no problem :D
