Program Download Links:
USB XTAF XPLORER - You must login or register to view this content.
Modio - You must login or register to view this content.
WinRAR - You must login or register to view this content.

After creating a theme with Modio there is no need to resign. You can call the theme whatever you would like but after clicking "create theme" you MUST save it with "theme" straight after. For example, if i wanted to call my theme Soccer, on the main create page I would call it Soccer but after clicking create theme and it asks me to browse where to save it, save it as SoccerTheme.

ENJOY +Rep if this is clear for everybody to understand
