Help for Running PC only plug-in on Mac

[DrGoo1]

Hello,
I have some knowlege of how Audiogridder, Crossover, and Crossgridder work but I am not able to get the single plug-in that I need functioning. The plugin is Jamstix4. I initially tried to use the 3 programs to run Audiogridder in the Crossgrider bottle. Everything works but the GUI for Jamstix appears on the Mac then disappears and only reappers with moving the GUI.
Next, I tried to just use Audiogridder with the server running on my network. I am able to see some plugins that load in Audiogridder (I have tons of plugins) but apparently, on the PC, Audiogridder doesn't load the dll for Jamstix4.
Jamstix4 is a very unique Virtual Drum Instrument and there is no Mac equivalent and development has stopped so there is no real support for it (although it still is commercially available and runs great on my PC).
Am I just out of luck with this? Thanks so much for any help.

Dave
