Reginald_Anselm_Le: Ever since I updated my Windows 10, there's been a strange glitch where every time I update the map and close it, it erases all data on it. It just becomes a blank page. I checked the maps on the other levels and they're all gone too.

The only other thing I've noticed is that the first note of the music gets skipped whenever I open the game(that little tune at the intro screen).

I can still play the game, but I kinda need the map...

Bookwyrm627: My first guess is the game has been installed in some kind of protected location. UU updates the map and writes to the file, then Windows reverts the change.

Reginald_Anselm_Le: I tried re-installing the game, but it didn't help. I still have the map filled in on my save file as I haven't saved the game post-map deletion, but I can't seem to find a way around it.

Bookwyrm627: Where is it installed initially, and where did you try installing it for the re-install?

Reginald_Anselm_Le: I installed it on both occasions to Program Files (x86)

Bookwyrm627: That might be a/the problem (though I'm not sure).

Try installing to a new folder, something like "C:/GogGames/UltimaUnderworld".

Reginald_Anselm_Le: ...
I just accidentally deleted my save file
oh well
