Last night the creators of AION SZ Bot decided to bank on this sudden found interest by the US Gaming community and change the exe and forced an update. All previous keys sold ONLY work on the chinese exe and you have to buy new bot time cards from botsmall. The issue is botsmall is not selling keys yet! /LOL So if you want to continue to use the key you paid for, just run the chinese version of the client using your key! Otherwise you'll have to wait till they get this all resolved.
