I just spent a few hours updating all my financial records in Manager, and backed up the file. All good.
Then I figured I’d better check your changelog to see if there was an update to the program, and sure enough there was, and so I installed it (deleted old version of Manager, downloaded and installed new one -15.6.19).
The program now won’t display my current records — I’ve just lost several months of entries (25 August is now latest entry). The Forum link says “Error”. I imported my backed up file, but that’s not changed anything — still have the same loss of entries (25/8 is still the most current entry).
I’m running OSX 10.10.5
