Download Problems

I am new to the Blackberry world and one of the Verizon workers downloaded iheartradio and Blackberry App World. I have used them both before and now neither of them are working. Blackberry App World just says loading continuously and never changes, and iheartradio eventually says cannot fetch configuration files and that I may have a problem with my network. Does anyone know what I can do to fix this? I'm very frustrated. Thank you!

Have you tried performing a physical battery pull? Give that a try. BBs need a refresher every now and again.
