So i started playing maple again after maybe 4 years... I find out that you can transfer your character from one server to another, so I got the 25,000 NX Cash but when I try to purchase the cash item it says something like not enough Nexon Gamecard Cash.

What's the difference and how do i get Nexon Gamecard Cash, I feel like a noob >_<

I think you buy it? I dont play MS but I think ive seen cards in stores. I dunno though.
