My DoIt for Mac has started to crash on startup. I click the icon to start the app, but get the "Doit.im quit unexpectedly." message after just a few seconds.

This only happens on one of my machines, the other machine, and the web version, are fine.

Looking in console, there are many error messages of the form

DB Error: 11 "database disk image is malformed"
DB Query: insert into zexception (zexception, zresid, zrestype, ZNOTES) values (:zexception, :zresid, :zrestype, :ZNOTES)

I suspect that I may need to reset some configuration or clear some caches or something. Any suggestions?

I've attached the crash report.

Regards

Glenn.
