Pool-x - Can't change my payment address

[gobes]

Hi,

I restarted recently to mine LTC on Pool-x.eu . I had a wallet on wallet.it.cx, but as the website is down, I created another one locally.

Anyway, when I try to change my payment address on Pool-x, I get the message "Authorization Pin is Invalid!"... but my pin seems to be valid: when I logout and click on the forgot password link, I write the same pin code, and I receive an email with a new password... so, what can I do ?
