Hoping I can get some help with this. I'm attempting to purchase a license, and every time I try to pay through PayPal it it displays the following error: I have tried different browsers. I've tried different computers. I've tried four different credit cards (Visa, MC, and Amex). I've different email addresses and different physical billing addresses for different cards. Can't think of anything else to try. I've also used the contact form (http://xenforo.com/contact/) to try to get help and have not gotten any reply (granted, only been about 5 hours). Couldn't find a phone number. Kinda frustrating. Any ideas?
