so this is my first time trying this app, i installed first with easy install and everything went perfect, i tried the game with some songs and mods and eveything was fine and functioning. once i put the megamix 39 skin pack by correllroy the game starts with errors and the skin doesnt appear. i somehow managed to get the skin functioning but when i go to play a song map, the map doesnt start nor the loading screen of the map. instead a error message appears that says "a fatal error ocurred. Please send "error.log" to the creator" what does this mean? is there anyway to fix it?
