So, your 15-45 is broken/faulty. Take it back where you bought it for replacement.

I have the lens that came with the camera. It’s the 15-45mm. I’ve tried to moving both pieces in the lens but it doesn’t seem to do anything. I’m pretty sure the piece closest was zooming in & out but it doesn’t do that anymore. 

Awesome!

Also, there's a setting "Shoot without a lens" that needs to be turned on for lenses with no contacts and adapted manual lenses, otherwise the camera won't respond to the shutter button when you have a manual/old/no contact lens attached.
