SampleMoog works fine for me on Windows 7-64 PC, running Sonar X2-64, and I am not using JBridge or anything else special for my 32-bit plugins.
You might want to try uninstalling, rebooting, then reinstalling.
Before adding to Sonar, run it as administrator in stand-alone mode so you can take care of any registration requirements.
What are your system specs?
SampleMoog tends to be resource-hungry ~ if you're running with minimum system specs, that could be contributing to your issues.
Also, recommend native ASIO or WDM drivers for your sound card.
In my experience, "fake" drivers like ASIO4ALL aren't worth the effort and unreliability when used with resource-heavy DAWS and plugins.
My PC is a 3GHz dual-core with 8 GB RAM - works fine.
SampleMoog has some AWESOME combi synth patches, so it's worth the effort to work through the issues, IMHO...
