[Q] HTC EVO LTE won't root...

Trying to root my HTC EVO LTE using RegawMOD EVO 4G LTE Rooter.exe

I've followed directions and tutorials. I have HTC drivers installed and .NET as required.

I start up the root software and it opens up to the phone. I set the phone to USB Debug and plug it in.

The software shows the root me button. I click it. The software says wait while your phone reboots..... Done.

Phone never reboots. My phone is 2.13.651.1 710RD

Any ideas what I'm doing wrong?
