I've been using with my MacBook Air with Mountain Lion for months with now issues.
Now when I go to launch the apps goes through all the normal processes (sign in, show blank page, display my layout windows). When its all done is closes the app.
I've tried the following:
Restart
Shut down and restart
Throw Logos app in the trash and empty trash
Install fresh version of Logos (stable)
I'm still experiencing the same symptoms.
I've attached the error log files as described in other threads.
Help,
Darin
