"Error loading Show"
I am 82 years old and am in charge of operating a UI24R in a small rural church. Everything has been working fine for a few years but suddenly I get a "Error Loading Show" message when I try to save a new Show and Snapshots. What can I do to overcome this problem? If I reset to original factory setting I fear I will lose the EQ, etc. settings. If I install an update, will I be able to retain the settings that presently exist?
