Fatal Error, "openlp return - 1"

GLJones

I downloaded the wrong version on my home laptop. (3.0)
To stay compatible with the Churches version, (2.7.4), I removed the new version and installed 2.7.4 which will not run.
I first get a database Error then a Fatal error, (openlp return - 1)
What do I need to do the correct this?

Did you uninstall version 3.0? My guess is OpenLP 2.7.4 is trying to open the database that came with version 3.0. If you delete the data directory I'd expect version 2.7.4 to open.

Firstly, there is no such version as "2.7.4" I'm not sure where you get that from.

Secondly, this is because OpenLP is only forwards compatible, not backwards compatible. You cannot downgrade.

Lastly, version 3.0.2 is the current stable version, version 3.1rc4 is the most updated version, and the last version from the 2.x line of OpenLP, 2.4.6, has not been supported in a couple years.
