The 10th of June was the last time JustDon posted and I think what was going on is that the Acknowledging link that appears when I connected to the Nexusmods website with Mod Organizer 2 also may occur when someone first activates the link to Nexusmods via Vortex.
If so then the reason for the problem that JustDon may have had was because of the Activation page not getting the correct attention when JustDon signed in with the Vortex Nexusmod link. Thus shutting down and requiring requesting JustDon to repeat the setting and retry!
I barely got to that point when trying out Vortex the first time. I went back to Mod Organizer 2 and realized the activation key from having it installed already was still installed in my computer MO2 folder. I believe that because I didn't fully uninstall the links to MO2 in the setup that may have interrupted even corrupted my Vortex experience.
I would advise anyone who has installed, Nexus Mod Manager or Mod Organizer 2 to make sure they clear the folder for the other Mod managers before they install and use Vortex for the first time.
The folder for the installation of the NMM and MO2 are in the AppData settings and need to be removed so that either of the Mod Managers do not have any left over coded stuff in the in their username/AppData/Local folder.
Is the Activation Key provided the same way with Vortex users as it is for Mod Organizer 2 users?
