i have this error alot. i was reinstalling, but it make me loose some configs. So i figure out another way:
go to this folder: ABfolder\Configs\Accounts
Delete a file with ur acc email. It works to me.
i run 6 accounts, one received a warning. All patron.
The account with warning was one account i had activated patron for less then a month, but all are old accounts from head-start.
AB works whitout beta key now. So far no warnings or bans
Trion messed up with theyselfs, CM made a post today to inform people. IDK if i can post AA forum link here, but if u search in forum you will find it.
