Does anybody know how to install a certificate for mp3's
 

when i have a song on my phone it has the piece of paper icon next to it. when i try to play the song it says "this mp3 is not signed with a trusted certificate. DOES ANYBODY KNOW HOW I CAN GET THAT DEFAULT LOGO (WHICH IS THE WINDOWS LOGO) BACK TO NORMAL WITH A CERTIFICATE

whoa...that doesn't sound like an mp3 to me...check the file extension. Are you even able to play it on your PC?

yea..i cant use it as a ringtone either
