Cannot speak for everyone but I have experienced this also and lost some horses on occasion. I now back up the whole so7 folder after every season and keep 2 or three incremental backups. I back up my export files after every export and check the file is populated before I export. I also usually keep dual copies of the backups. Once bitten twice shy

This is good practice. I copy all my save files except the replay files into date named files once the new 2yo enter the stable.
I have found when I have been using the ck to trial then back out and open a game it very often crashes and the .db file is then empty. Now after using the ck I close the program to avoid this happening until I forget. Fortunately the .bak file is still there so I copy this to the desktop and rename .db then replace the null file in the save folder.
