Sonar 5PE Drum Presets

Sonar 5PE is up and running. Thanks for all the help.
I have a drum map issue.
In the Drum Map Manager there is a preset box. Tutorial 9 instructs me to click the presets dropdown arrow and select GM Drums (Complete Kit). But the presets dropdown menu is empty.
I suspect this may be an install issue but could use some feedback.
If it makes any difference, I installed 64bit version of Sonar 5PE
Thanks again,

Raybros
