Interesting concepts, thank you everyone.  When I get home from work I will try all of these ideas... none of them sound too difficult.  Thank you

If you have Sonar X3 or earlier, try to open the project with it.
I have had success opening corrupted Platinum projects in X3.
You will get a message saying the project was saved in a newer version of Sonar and you might lose some features, but it saved my butt!
 
 

AFIK there isn't anything in the last update that could have caused plugin incompatibilities.
Have you tried rolling back to verify this theory?

Thank you to everyone for responding,... Dan was right... the update from EWQL Spaces put the new dll file in another folder.  I simply copied it to the one that Sonar scans and bam everything started working.  I have probably used up my quota of questions for one lifetime, but now that I "rolled back" the version of Sonar (to see if that resolved the issue) I can no longer find a way to reverb forward to the newest version... Does rolling back lock everything in time permanently or is there another way to update....?
thanks again... this forum and the people in it are very helpful

the newer version should be right there in Command Center.
what version is listed in CCC ?

Alston is the version that's running right now... it shows the latest version (or the current version) on the CC front page, but there's no active link to update to the newest version.  When I right click on Sonar Platinum it shows that I am running the older version, but all the text is green indicating that there is no update available.
