Hi Everyone: A couple of days ago, I was suddenly unable to play Slacker, Pandora or my regular MP3 music files. Slacker would load, but the songs would not play. Pandora would give me an error message and my regular music player suddenly would not recognize my music files. This all happened suddenly after working fine the day before. I did some online research, but nothing seemed to match all my symptoms. I went to the local Verizon store tonight and they said I had too many apps running. They installed Advanced Task Killer for me, killed my "open" apps and everything works fine now. They recommended that I run it at least once a day. Does this make any sense? I keep reading that we don't need app killers. Thanks!
