Just installed Minion back and :
- Minion won't see the manually installed add-on, despite pointing on the right add-on directory
- Minion doesn't show any mods in the "Find More" tab.
Checked the firewall, tried to start as admin, reinstalled it, etc... nothing works.
Please read the sticky thread in the Minion forum, named Troubleshooting.
If following these steps does not help provide us your Minion.xml and minion.log files please, as the other sticky thread about posting errors tells you to do.
