I paid in December for this program and you applied it to the former program now you are asking me to pay for the trial which makes no sense. Call me at 360 539 5011.
You will have to contact the official developers in order to find out about the issues you're having with the payment methods. This is a matter that only they can provide details.
Luckily, if you have this software, Premium support is enabled for you: http://www.iobit.com/en/onlinefeedback-form.php?product=pro
Select the product, and then the type of problem and fill the form.
Regarding your question, please contact firstname.lastname@example.org. They will help you look into it. Thank You.
