Hi, you are using the pay function from the friendvista homepage which was the original method. I just checked it and it doesn't appear to be working for me either (I will raise with admin). However, the link I gave you above is a better method. You get more bang for your buck so to speak.
Did you read it? Basically if you use option which is via Paypal (just make sure you put your username in the message box so they can identify your account) you get 20% extra on your points.
If you use the second option which is to buy an Amazon gift card and follow the steps outlined (just make sure you give the following: Your Name: your username on VIPTV.NET and Recipient E-mail:
lbjedward@gmail.com) you will get 50% extra points.
