Hi, I downloaded the crazy enchantments plug-in and it works fine but when i want to buy magical fixing dust or a scroll i needed money. I downloaded a towny plug-in too to buy the dust or scrolls. Then i got enough money to buy them but then it said that i didn't got enough money. Is there an another plug-in for this or can i edit the files in file-manager so i can buy them with xp?
