PSP L'Otary (Rotary Speaker Plug-In) crashes SONAR Platinum

Everything was working fine in Platinum until I installed PSP Audioware's L'Otary (Leslie Speaker simulation) plugin.  It always crashes SONAR when I instantiate (is that the word ?) the plugin, and I have to forcibly close SONAR down.  Both Platinum and this plugin are very new, but I think it's the PSP ...
I'll contact them next week, but wanted to give a heads up in case anyone else was seeing this.  Anyone else ?

Thanks gustabo.  I've already opened a ticket with PSP, but they'll be out until end of January at the NAMM show.
Not a big deal ... I got a few alternatives :-)
