There is a problem, i'm trying to change my music and it says Could not set permission to file, even tho i used a WAV and i tryed a non copyrighted song T.T, please help :D

(Sorry, So the solution was apparently the non copyrighted song was copyrighted, i managed to change songs... i'm sorry about the Thread, i'll try to close it, i had searched it before like the rules suggested... idk if we can delete threads [i searched] so i'm still sorry)
