Galaxy was previously up to date yesterday and working. Upon starting it a few minutes ago it updated itself and promptly crashes with "Fatal Error" "Failed to load game database". The UI wont even start up at all now.
Have you opted into beta updates by any chance? https://www.gog.com/forum/general/gog_galaxy_official_discussion_thread/post1566 http://mantis.gog.com/view.php?id=5714
I previously used the beta for the last few years, but I switched to non-beta recently and it solved some problems. After uninstalling Galaxy, downloading the latest client download and installing it all problems went away however, although I had to reimport my library as per usual.
No, Windows 10 updates don't install on Windows 7. :) But yes, I have Windows 7/x64 fully updated prior to the Galaxy update. Galaxy would not start up at all, including after a reboot though. I had to uninstall it, download the installer and reinstall it, then re-import my installed games and it worked properly. It updated itself again and seems to work still.
Ah right, I forgot you had Windows 7, my bad :) So everything is working for the time being, right? :)
Yes, with 1.2.41 stable, things seem to be working fine now. :)
