Please use the Minion forum here then:

Perhaps you'll find more assistance in there.
Try the 32bit vesion of minion.
Start minion as administartor.
Try to reset the game checks inside minion and choose your game folder again, top right corner.
Allow minion in your firewall rules and exclude it from antivirus checks.
Then post your minion.log file and minion.xml file if theer are still no addons shown inside minion.
The Minion support should be able to tell you what's wrong then.
