you shouldn't have any problems setting up the mini.its quite simple with usb loading.
you just extract the file from its compressed folder as always,like you did with the 2500.
then you just put the file on a usb stick.just drag and drop.then take the little usb stick to your mini that stays right hooked up to your tv.press menu and go to usb.then click on update.then very very fast.(must faster than cable/loader that your used too) it updates.and your done.
its a fairly easy unit to use.but more complicated than some.
here is the loading instructions:
