MO 2 and LOOT: LOOT throws out error

[LadieWinter]

Hello!
 
I am attempting to use MO 2 for the first time since I have read that MO will shortly become obsolete. I'm not exactly installing STEP: Core or STEP: Extended, but I have been using the pre-mod installation instructions since I have been out of the Skyrim game for a few months now and my mind is a little foggy.
 
At this point, I have not installed any mods what-so-ever. I have reached step 2.A. after having followed everything else. I am able to run LOOT just fine, but once I try to run the sorting function, it instantly throws an error at me. I cannot even begin to figure out what this error even means. So, I am hoping someone else does.
 
Some other information I hope is useful:
Running latest Skyrim version
Running all DLCs: Hearthfire, Dawnguard, Dragonborn, High Res Pack
LOOT Version 0.12.5 (I originally installed the LOOT from the original LOOT site. I then uninstalled that one and reinstalled the one from Nexus to see if it made any difference, but it did not.)
Mod Organizer 2 Version 2.1.3
Like I said, no mods installed
 
Here is the error message:

I've never had any problems with using LOOT and the original MO. : / Any and all help is greatly appreciated!

Well, ok.

I guess I fixed it. I ran LOOT outside of MO 2 which allowed it to run. I then went in and run it through MO 2 and now it works. I don't know why it doesn't like being run through MO 2 first because I have never seen that error with the original MO.

 

I guess this thread is obsolete then.
