[cents]

Same thing here (I already sent in a bug report via email). What's special here is that I have an alias of OmniFocus.ofocus inside the AppSuport folder, pointing at the real file on my USB stick. That worked well until 1.0

Edit: I can't launch OF 1.0 at all, it crashes on launch.

Edit 2: Works now. I copied the last backup to the stick, renamed it to "OmniFocus.ofocus", deleted the alias in AppSupport, and set the database location in the OF preferences, pointing to the stick.
