Opening a a project, SONAR gives me this error message three times before opening the track view.  Everything seems fine after that.  What is going on?
 
Thanks,

It is likely plug-in related. It is possible to isolate the plug-in(s) throwing the error by opening the project in safe mode and selectively disabling plug-ins. To invoke safe mode hold the SHIFT key while opening the project.
 
I encountered this error once with Cakewalk Sound Center. Re-installing the plug-in fixed the problem.
