Nokia :: 5800 Xpressmusic - Music Player / Library Freezes After Updating To V40

When i play music from the all songs option in the music library the music player completely freezes all the time after a few songs. This happs when as soon as a new track starts to play. then the music app does not close/exit too.no problems when playing music through playlists and by genre.I have to close the music player by force by using the remove memory card feature which closes all running apps. to play music again to use the phone.is there any problem playing music in wma format? i checked the file details in the music i was playing when the player froze.
