Tool table crash after reboot or power off

Hi all, i have a problem.
If i open tooltable to edit tool and  power supply goes out tooltable is crashed,
If i open tooltable to edit and go to shut down my pc, tooltable is crash.
How to fix it problem?
The power in my workshop often suddenly goes out because the electricians are repairing the old network.
 

How about a UPS for the pc.

I understand this, I'm trying to explain something else. If the tooltable program did not complete correctly exit, then the tool file is corrupted. There is no backup. Backups must be made manually......

if I'm working with tooltable, minimized the window and need to finish work, then I turn off the computer and tollyable file is corrupt

I suggest adding a change, when the tooltable program starts, it makes a backup file of the main one, if the program starts and the file is damaged, it suggests opening the backup file
