SessionDrummer loads kits/samples no problem, but when I click into the step sequencer, no samples are present.  There are some, presumably, midi note names in the rows, but none of them play anything.  any thoughts on what I'm doing wrong?  I haven't had this problem before, but I've never used step sequencer on this particular install of Sonar.  I normally do my sequencing on a laptop and step sequencer has always loaded the samples automatically.

Here is the process I just used in X3 which worked:

1. Open a new project in SONAR
2. Drag Session Drummer from the browser to the project creating an instrument track
3. Load the Smart Loop Groovy Kit program from the Acoustic kits in the Session Drummer browser
4. Click on a few of the kit pieces to make sure there is sound
5. Open up the Step Sequencer, click a few notes in the sequencer
