I have installed the free version of George through the link onto another PC and run a backup into it but had the same problem as before.
Don’t know the free / not free version would make any difference as my original version of George is not the free one. However I can’t uninstall that without a way of getting it back
If you go into the C drive on your computer, there will be a folder named George. Open that and hopefully you will find copies of the backups you have done previously. (Hopefully you have done backups.)
I have a folder named "backup" but I also have other backup files. They have 2 letters, then 2 numbers, then 1 letter followed by .GEO
Try to use these backups from before the system failed.
