Win10, BW 10.4 and 10.6, latest 10.0.8.710

After having been OK since May 2018, suddenly a few weeks ago program stopped working. Initial window comes up, claims to read ini-file, loads something and then disappears. Tried to completely uninstall & reinstall, same problem. Cannot find ini-file when asking to edit it (shift/double click / tried all recommended actions in there as well).

Any clues what I can try nextů.

Best regards,
