usalabs,
When you get a chance, could you please outline what your setup is? You mention Wavetable above but it would be great to know a little more. Using the "Snipping Tool" found in Windows 7, the easiest way to show us this information would be to capture an image of your Midi/Audio driver setup.
To this, go to "Opt" (#1), select "Preferences". Now click on the "Midi driver" button" (#2) and then save a capture of the screen that pops up (#3).
For example, below is my setup.
To upload the image, use the "File Manager" option found in the "Full Screen Reply" dialogue box.

Regards,
Noel
