Still I wait to get response from you (I ask this question many times) for my question:

Whats wrong with my Signature - because I did exactly what you said on first page and get 3 payments in a row without any problem and updated my signature with new one.

Please explain about it, I can fix it soon. 

I think many people here wait to get answer from you, to this question.

Try to pull confidence in this SIGN community.
