I know this sounds kinda weird, but a few days ago, whenever I tried to start up the game, it would act like it's beginning to start an update, but then it just didn't go any further from there (the version I had was 4.26 or something like that, and it was trying to update to 4.58).
However, when I went to Last Moon's folder and clicked "update" (because I thought that maybe it would update then), it suddenly said that it could not find the .exe. Every time I try to start the game now, the update screen pops up as usual, but then it says something along the lines of "Cannot find LastMoon.exe", and then it closes really fast.
Does anyone know what's going on? Sorry if this sounds confusing.
