Missing Plugins

I just updated from Cubase Artist 7.5 to Cubase 7.5. I reinserted all the plugin paths, and if i open an old project i can still open and edit the libraries already in the project. But I go to Add New Instrument Track to the project or in a new project, all that i have as options are the preset Steinberg instruments like Halion and Retrologue. None of my 3rd party libraries or inserts are available. Yet in the plugin information tab, it says that i have all my 3rd party plugins in Cubase. They just aren’t showing up under the Add New Instrument Track. So i have no way to add new tracks unless i go to old projects that happen to have exactly what i want already in the project. How can i get my plugins to show up?
