mbox 2 pro usb won't power and asks for ilok on install

[[email protected]]

trying to install le 7.4 on a intel mac. but upon opening the software. the dialogue box asks me to authorize. clicking authorize it's asks for an ilok. i have not even entered a serial code any where. the box won't turn on either.
i did buy this box from ebay but it came with everything.

on the first install i did pick to install every thing instead of just the protools it self should not be a prob since i just wanted to check out the demos any way

thanks in advance i did try to look through the forums!

thanks
