Same here, i have also problem on Weexchange with 2-Factor. They have strange interface for that. Hope support will get me out of trouble, but i am already waiting for about 14 days

Well, now you tell me your having a 2-factor problem.
Your pm's only asked about the lockout message, and then stated you couldn't login. (Which is why I just responded to you asking if you recently enabled 2-factor.)
To fix a stuck 2-factor, do a password reset, and pm me the reset code. (Don't actually change your password.)
I will get it fixed up for you.
Also, WeExchange has a new website, and has been beta testing its new trading system that has huge BTC trading volumes and proper market prices available for CAD and AUD.
If anyone is interested, pm me.
