PanelView Plus 600 - runtime not communicating

When I test my RSView ME screens on my PC they work fine but when I make my runtime and download it to mt PV600+ the screens don't work (indicators don't change color and pushbutton don't do anything).

I don't have any "error" messages on the screens. I pinged the PV600+ and its there.

Any suggestions on what I might have changed to have it stop working? (It was working yesterday but I've cycled power, downloaded a few times, and maybe I changed a setting somewhere whe I was working)

RSView ME V4.0
CompactLogix V15.0

Do you have different online paths from the PC to your PLC to the path from The screen to PLC? Have you changed your comms settings?

When you ping the PanelView Plus, does the IP address you use for the ping match the IP address that was in the program you originally downloaded to the PanelView?

If you cycled power, you may have returned the PanelView's network settings to DHCP, and the PanelView has picked up a different IP address from your network.
