Well.. I have started to encounter this now that my CE time has run out.. Yay.
Stupid square, anyway. I was looking around the forums and found a similar thread so I brushed through it.
Found the little Ultimate pay website suggestion, unfortunetly after I register and I need to click my email to "confirm" the account, it does go and says "Unrecoverable error" and that support is being contacted about this but I cant log in or do anything with the account, attempted it twice.
Any other suggestions of websites or services we can use? Unfortunetly I cannot buy the physical cards so I'm screwed on that end.
