Have installed sp 1.4 for CS 777 . Got some issues:beacon,NAV,logo buttons are not active,  fuel pumps, battery, APU GEN , window heat buttons and many others more on the overhead panel aren´t active either.
When I run FSX , MCP panel reads these messages : ELEC AC BUS R, ELEC AC BUS L , WINDOW HEAT, EQUIP COOLING OVRD , TRIM AIR R/L,
PACK R, PACK L, MAIN BATTERY DISCH , etc.
The thing is this plane used to have  a 2D cockpit  thru which I accessed FMC . How can I access FMC now? Thru virtual cokpit?
