Will no longer open in OS10.8.6

After initial success opening .cwk drawings, LibreOffice will no longer mount in OS10.8.6. I have tried reinstalling with no luck.

Which LibreOffice version?
Does the task manager (I always forget the name in OS X) show the application running?

It’s LibreOffice No, it does not show that it’s running. I click on it, it bounces once on the dock bar, and… nothing.

Eureka! I threw out LibreOffice, downloaded the “stable” version and can now open my .cwk drawing files!
