I've changed the lightning install.rdf file of the 0.9pre version before installing it.
So now, the 0.9 lightning is shown as 0.8 at the add-on listing.
This avoids the BirdieSync Error message, that a non-supported lightning version is used.
But synchronization does not work. There's an error message at the BirdieSync Options telling me, that "The time zone is not defined in the current profile, although it is defined there.
Seems, that it is really incompatible...
