could be a glitch in their scripting. Haven't used the paypal option yet (been getting cards locally, or going direct through Playspan for their deals like this weekend's $25 code for $22)...but with some systems they send you to log into your Paypal account to authorize the charge. If they're doing that, there could be an issue linking to the other server or something.

If you've setup the email account for Playspan through the SE portal (it should prompt you to do this if you go to the UGC payment tab, not sure if it prompts for it on Paypal tab), you will earn a free 100 Ultimate Points for Playspan. They'll send you an email for setting up your password on the Playspan account and then you can try buying a UGC code through them to redeem for Crysta.

It's a nice deal atm....those Ultimate Points (UP) can be redeemed for Crysta when you go to redeem the UGC code. 100 UP=100 Crysta. It will prompt you to redeem the UP when you go to use the UGC code, so you tell SE you want to add 2600 Crysta, redeem the 100 UP, then the 2500 UGC code. So, if you are a new account, you could actually add 2600 crysta for only $22 this weekend ($4 free)--if not new, it's still a savings of $3 on $25 worth of Crysta.
