SML Believes Installed Game Too Old

Trying to get SML installed to use in Satisfactory 1.1. I just installed Satisfactory today (I wanted it on my nvme drive so uninstalled and reinstalled).
I tried to launch with SML enabled but get a launch error "Plugin 'SML' failed to load...."

I double checked the installed version of SML and that's when I noticed that the latest available SML version is 3.11.1 but the installed version is 3.7.0. When I try to install 3.11.1, it says that the installed version of Satisfactory (FactoryGame) is too old.

I've tried uninstalling SML and SMM and reinstalling both but SMM continues to force install 3.7.0 of SML.

When I launch Satisfactory from Steam I'm obviously on 1.1.

I attached a debug log.

Thank you for the help in advance!

Solution:
Completely delete any leftover

folders from old installs - check old drives where the game may have been installed in the past. Simply uninstalling the game from Steam does not remove the entire install folder.

Delete old profiles in SMM and create a new profile.
