I received an email this morning, although I think my client received it last night, letting me know that they reset my PC renewal as a purchase in my account so that I was able to use one of the accepted credit cards. I guess they didn't expect Visa or MC to be like that either. I'm just really glad that something was able to be worked out, and that they were so quick about it. Maybe my faith in the 'System' is restored. ;)
