Hi everybody,

I found the problem and i explain you (sorry for my english i'm not english)

The problem is the validation code (captcha). The captcha on the log page is not the good. To found the good captcha, simply open a new window with this address : https://bter.com/captcha

The captcha is not the same. After return on your log page and you see that the captcha has changed. Now you have the good captcha. Write it and enjoy
