[GNC] Help please. Upgraded from 2.3.4 to 4.12. Worked fine. But database does not load. Win 11.

Indeed, if you were truly running 2.3.4, you'll need to step to a 2.4.x 
version, then a 2.6.x version, then 3.x, then 4.12, running Actions > 
Check & Repair > Check & Repair All when first opening the file after 
each upgrade, and of course ideally, keeping backup versions each step 
along the way in case something goes wrong and you have to take a step 
back rather than starting over from the original file.

Adrien
