If Studiometry is attempting to load and getting stuck at the Loading Projects step, it is most likely related to your data location settings.
We recommend quitting Studiometry (or force quitting if necessary), and then relaunching the app while holding down the Option/Alt key to bring up the Data Location dialog box. From here, try selecting either your default data location, or your previous custom location if its already been set. This should help Studiometry get past the issue loading the data location.
If this does not work, try Quitting Studiometry again and then deleting the following two files:
If you do this and you've already set a custom database location, you'll have to reselect it to correctly load your data.
