Error with checking "STATS" on the menu bar

Hi there, I’m encountering issues whenever I want to know how many cards are due the next day. Each time I click on the “STATS” tab I get this message: “Invalid data found-please use database to fix the problem”.

This error has never occurred before and it seems it has surfaced after I had updated the software.

Any advice much appreciated!


You can fix it using the Check Database option in the Tools menu.
