That was worth a shot! Thanks, but no luck. And fwiw, this does not seem to be just an Ignition problem. It happens everywhere.
Here is a table I just joined now with Flopzilla on top showing how all the info disappeared.

So the problem seems serious and I'll just take it to my tech guys tomorrow. It'll probably take a reinstall of Windows 10 again, but oh well.
Thanks though!
