Making Studio One 3 Professional recognize EZ Drummer 2 / Superior Drummer

I searched for the answer to this but everything I have looked at doesnt address my issue. I have Studio One 3 Professional. I have Superior Drummer 3, EZ Mix and Helix Naive. Upon start up, my helix native shows up under "line 6". Toontrack shows up in my VST plug ins, but the folders are empty and I caot access any of my EZ Mix or Superior Drummer files or audio sounds. I am sure that I must be doing wrong but I caot figure it out. I have gone to "options", "locations" "VSTplug ins" and ToonTrack does not show up under an accessible folder.

I dont know what else to do! I have been fighting with this for hours now.

Second questions

When I want to add my drums, do I do it under "instrument track"?
