I also tried to play the newest update and at first it just wasn't letting me start sessions or open the tag media bit, but eventually I sort of got those working. But now it's just quitting the game every time I try to add/change tags on images/videos, and the application won't open anymore
Edit: nvm I think it's fine now, it seems like it makes a difference if the files are marked as hidden or not, even if they're visible?
