I tried to uninstall the app didnt know how! it wasnt on the Uninstall programs (control panel) found out it was on the start menu, uninstalled it, installed it again and seems to be okay...! Thanks for the tip and for the help!
I installed the latest updates, connected to with a microsoft account, included them in the library but still nothing! It used to be okay and i used to play my music on this app... but one day it simply stopped! There is nothing in my collection and i dont know why...
In my music app there 's no music, i 've added folders with music in the music library folder but nothing! It used to be okay i think! Its frustrating to have this app and no music in it to choose! Does it have anything to do with Network & sharing?
