''Unlock Gold trading error!''

Dear pwi,

Today I tried to sell Gold at the Auction House, after I figured out how it works I stept on a problem.
The problem is that you need to Unlock the gold trading before you can sell Gold. I went to my banker, what I have seen in other topic's, to see what my password for the banker was... but I didn't had a password, so I made one.

After a relogg.. I tryd it once again. I putted the same password as I have in the banker, but it still saying Password error.
My next step was World Chat my problem, some had good solutions... But nothing worked for me.

My question is;

Is there a way to reset the password for Gold Trading? I might have putted something in it while I were lower lvl as now. It's the same as my attributes, now I know that a barb dont need magic, and while I started I putted 30 points in there... Now I'm lvl 100 I know that you can buy a reset for youre points, but sadly there isn't a reset for changing that password...

Thanks for reading, and I hope for a quick response to solve my problem! :)b:surrender

Ps. After I world chatted someone sayd to me that I must not buy accounts... This is my first account I made, playing for a long time, and it defenatly IS my account!b:angry
