Too many failed attempts. Your activity has been reported to the administrators

My 6-month membership will expire soon. I tried to buy new one, but there was something wrong with paying procedure. What I have to do now as I got the error message written in thread title?

Hi Veiko,

We have had problems with fraud in the past, which is why you received this message after some unsuccessful payment attempts.

Please try again tomorrow. We apologize for the inconvenience!
