Cashculator start with the following error message:

This means that Cashculator can't find the database at the custom location that you'd previously selected in its Preferences.

Here's how to reset Cashculator's database folder preference:

Please open Terminal and paste there:

   defaults delete com.apparentsoft.cashculator CCDB_Folder

Then launch Cashculator and see if it loads ok.

It will launch with database in the default location, so if you want to use a custom one again, change it in Cashculator's Preferences.

We'll address this problem better in a future update.
