I accessed the EN World store from the EN World website, and tried to buy the subscription, to the War of the Burning Sky, and a Ptolus accessory. On both my PC, and my Mac when I choose the option to pay with credit card, it comes up as an unaccessible web page. I would think it was something on my end, but its happening on both a PC, and a Mac. I hate Pay Pal, and would love to give you guys more support / Business.
Here is what I get on my Mac
