DirectWave sampler and Sonar preset issue

I'm having a problem saving presets in my DirectWave sampler in Sonar. I'm getting a Windows Microsoft Visual C++ runtime error message as soon as i click to save as a preset, then Sonar has to be closed and restarted. I don't have this problem in any other hosts when using DirectWave. The strange thing is that occasionally it will let me save - but as soon as i try to open the preset later- i get the same crash scenario. Anyone have any ideas?

Thanks,

- Billy
