Unable to Find Hardware on Mac mini and Protools Express. HELP!

I've been working with this setup for three years without problems.



1) Mac Mini running Mac OS X lion (10.7.5) 16 gigs of Ram



2) Mbox Mini (3g) with Protools Express



3) Yamaha MG10/2 Console



4) Stageworks LD3 Condenser Mic



Yesterday I decided to leave the Mac Mini just for Protools. I initialized the Internal Drive, Installed Mac OS X lion from scratch and re-install Protools Express. Now I'm having this message:



"Unable to find hardware, please make sure is turn on and try again"



Everything is turn on as always, I tried different USB cables, different USB ports and I try the shutdown and let it rest for a couple of hours method to see if I can work again. I even hold the "N" key while launching Prottols to see if I will be able to work with my Protools again. no luck.



This is the list of things I did already:



1) Uninstall protools and re-install it

2) Install the latest driver for Protools Express and MBox Mini

3) Hold N to launch

4) try different USB ports

5) try different USB cables





Any help will be appreciated and if you make everything work as it was a "Paypal gratitude' will be sent.
