I'm still having an issue and no one seems to know why: I've been able to pay with paypal for a long time, but in the past month or so, when I go to pay through Avantgate with paypal (via their popup window), it won't login and says my paypal login details are invalid. However, when I go directly to paypal.com I can login with the same details no problem. Both DBC and avantgate say it isn't an issue with them (even when I show them the video of being able to go and pay with paypal through avantgate at another service, imagetyperz, which, in this case, instead of a popup window, takes you to the main paypal site and works). It's frustrating to me because DBC is still the cheapest around.
