Had an awful time trying to re-sub today. I've never had a problem using my card before but after being un-subbed for a while I tried to re-sub today, and I got this error like 4-5x. Not only until I did some research (i.e, found this thread) and checked my bank account did I discover it takes £1 for each failed transaction? That's pretty lame. Any way, managed to finally buy some subscription time via crysta using ultimate pay. So if anyone is having problems with your card, try that!
