1.) my first problem is that i can't select any midi devices because i guess i don't have any (picture below). However, when I use my originally installed Cakewalk, I have no midi problems. How can i fix whatever my problem is?

2.) how do vst plugins work? I installed a pack and tried to select it with Cakewalk VST Adapter, but that never seems to work.

3.) I guess that's basically it. I'm trying to make Sonar work, but I have no midi outputs, no vst plugins, and no idea how to fix that.
