I have installed your beautiful freeware B777-323 American Airlines .
When I press shift +2 the radio panel does not show up only a black panel with on the bottum the knobs cm1; cm2 etc. On the pedestal the frequenties are not in the windows
Also when I have the EFIS panel on screen when I click to change to STA; WPT etc ; nothing is changing.
Please can you tell what I 'm doing wrong.
Regards
