my bbm display pic

okay I have a 9320 for like 2 years now and my display pic stopped working after I uninstalled bbm and when I created a new yahoo account and used that one for bbm....my display pic hasn't been showing since then. I find it so frustrating and it just drives me up a wall, I hate it when someone has to ask me '' send me a photo of you or put up a pic of yourself'' or when they say ''your dp isn't showing...you know that right?'' so can someone like please help I tried EVERYTHING!!! I even changed my settings and stuff ----------------------------------- HEEEELLLLLLLPPPPPPPP??!!------------------------------------
