Lost data in Grindstone 3

I have been using Grindstone 3 successfully for a long time (2019) and saw no reason to move up to Grindstone 4. This morning after my computer did Windows update, Grindstone informed me that the old database was not access and created a new database… which means the old data is gone!!! I can see a new “empty” file from this morning, and I can see a file gsjdb file that is so small it must be empty.
Is there any way to recreate or recover the file from BEFORE the system reset this morning???
Thank you for any help.
