<br>Thanks Raoul. I have found a version of OpenLP that works OK on this old Macbook, and surprisingly, Open LP opens up much faster on it than on a fairly new PC (about 2 years old), so because of some issues we were having, I would like to start using this old Macbook. However, I've run into a slight problem. I've transferred all our data files across, but when I try to open OpenLP, it tells me that the database is in a newer version, so it will not open it. Is there any way that I could convert my song database (which has a huge number of songs in it) to the older version?<br><br>https://www.dropbox.com/s/b93l1w0hwnrvly1/Screen%20Shot%202017-12-09%20at%2023.31.29.png?dl=0<br><br>This is a screenshot of the warning I get at startup.<br><br>
