I just wanted to update this thread, in case others run into the same issue.
I finally figured out what was happening, and why the drivers were not installing correctly when doing the install for XUnlock Tool. It was the nasty Windows 8 Driver Signature getting in the way!
All you need to do is click the Gear icon, go into Update & Recovery, then Recovery, click Advanced Startup and Restart. Once the computer restarts select Troubleshoot, Advanced, and Advanced Startup options. Click Restart. Hit F7 and restart.
Good to go after that! Let the ROMs begin!
