I just updated Sonar Platinum today to Kingston Update 1.  Now when I went to open the most recent project I've been working on I get this error everytime.

I've tried a few other sessions and they seem to open fine.  Just this one is having issues.  Any idea what could be happening here?

Alrighty....well I just solved this in a peculiar way.  I opened the cwp file in safe mode using <shift> and clicking on the file.  I loaded the file with no plugins.  It loaded fine.  I then closed and re-opened sonar and reloaded the cwp file normally.  Everything loaded up fine this time all plugins active.  Weird.....
