Hello Jon,
I have just received my second notice that my payment for Instant Article Wizard has been cancelled. I sent an email to you about it at Yahoo, but have never received an answer.
I had phoned PayPal and complained because I have belonged to PayPal almost since they started and never once had a problem, they said there is nothing wrong with my account, and the problem might be yours as often the vendor does not know that payments have been cancelled.
