License already in use? : General & Trouble Shooting

So i got Prem. Upgrade downloaded XUnleashed and everything works great and then it starts to freeze up when i change my Windower Resolution for FFXI so i decided to delete everything and try and reinstall and did great but when i try and put my Reg code back in to regester its says "License already in use.". So anyone know whats up?

if you dc from the server you need to wait untill the server refreshes for you to use it again

when does the server refresh?---

EDIT: NM i just tryed agin and i regestered TY for the help ^^`
