I can't seem to get the latest snapshot version of Arx Libertatis to work.
I extracted the new .zip file over the game files.
The game doesn't even start anymore.
The game was installed on its own, without GOG Galaxy.
I also tried a different approach - installing the older AL mod.
It doesn't help with the runes though - I can't light the torch in the area after beating the goblin and falling through the pit, where the game teaches you about the runes.
The game even seems to recognize the magic strokes - they appear on the upper-right corner.
But the torch wouldn't get lit.
Then I tried installing the latest snapshot over the game - and that didn't help at all.
Then I tried installing the latest snapshot over the older AL mod, and the game still wouldn't recognize the new options.
I did a clean install with each approach.
Any help would be appreciated.
If using Arx Liberatis, disable V-sync, it's a known bug it borks magic casting.
