Unable to locate hardware - Help!!

Hello,



I just purchased the AKAI EIE PRO which came with Pro Tools Express. I installed everything onto my mac late 2013 OSX 10.9.2 (ILOK is ok, installation is complete,...)

When I want to start Pro Tools Express there's a pop-up saying: UNABLE TO LOCATE HARDWARE...

I tried plugging it into another USB-port, but the problem remains...

Anyone?
