I took the OTA and I lost root. I have been looking for a solution and I have tried searching for an answer. Can someone help me with this?

I have been trying to use the LG_Root method
Description that I was trying to follow can be found here:

I am running Windows 8.1 64
I have the ADB drivers loaded.
ADB sees my phone
When I run the Ports.bat file I get this:
C:\WINDOWS\system32>reg query HKLM\hardware\devicemap\SERIALCOMM
ERROR: The system was unable to find the specified registry key or value.

I have done a manual search of the registry and I am not able to even see this in the registry.

Can someone give me some help or point me in another direction so that I can re-root my LG G2?

Thank you
