Same experience, but I find the more I try the less it crashes. Maybe
restarting the app does something that eventually gets its data file
going right. Or something. Frustrating because I can't find a
pattern, except it's always the same error message and it's only right
after installing. When I installed the upgrade today it crashed
immediately, then again after I relaunched the app, and now I can't
get it to crash; same as with the first version. If you haven't
already, email the developer the text of your error message.
Kudos to the developer for the 9.1 improvements:)
