Some of us were running into the issue today where you tried to recharge your Daum Cash from the Pearl Shop. When you went to pay either through paypal etc, you would get a page that read "Internal Server Error" and you could not complete the transaction. Solution: Go to the BDO website, if you are logged in, log out. Then log back in on the website. Make your Daum Cash purchase from the website not in the shop. And it should work that way. My guess is they have some server routing issue from the cash shop to the website.
