I've just tried and still there is no log. Can this happen because of the diacritics in my Windows username? I know it can sometimes cause some problems with apps but I don't know if that's the case here. Just a thought :P
Edit: I don't know if that helps but I noticed one thing. The first or second version of the game created a folder in AppData (although the same problem existed). Now, it doesn't (Idk if it should). Basically, my idea is that maybe it also created a log?
There used to be a folder for preferences and saved data. I moved it to the app folder because it seems people aren't using the programs folder these days.
It works here. I am stumped and can't find much information. I must fall to trial-and-error on this one.
Well umm... still the same problem. But, if you say that you are confident that it should solve the issue, then maybe I lack some additional software which is needed to run the game?
