Seeking some advice. i have had a working Apex controller for 4 years now. Today i went to access the Probe/Input Setup under the Configuration menu and the system hangs at the loading screen and i cannot access the probe setup menu.

All other menus and sub menus in the Apex work fine. I am logging in via CAT6 cabled connection.

Running latest 4.53_AB17 firmware.

Troubleshooting advice much appreciated. i have 3 x PM1 units connected as well as a leak detection module and a few BoB's.
