MOL points from netopia then go to MOL site to get GASH cards then go to GASH HK site to load it then go Elsword HK top p site to convert it to "in-game cash" aka "G"
I buy the prepaid cards from a (real life) retailer for GASH or ask a Netopia front desk clerk about "MOL Points" then they'll just ask for a denomination (100, 300, 500, 1000) that i want to buy then ill give them cash and i have the code for MOL.
Depends on your location, if you are in the Philippines or any other country outside HK you can easily buy a GASH card through an alternative site called MOL Points. Fairly easy to buy credits in this site and safe as well and no need for credit card too.
the patcher itself has a problem, stops like a retard then you have to start over again, more likely do a manual patch or just read through the other threads like the Elsword Hk Updates to see if they have the latest patches...
