You need to hold down the "Gyro cage 1" and Gyro Cage 2" buttons for 2 seconds then release, the error lights should go away

Grupp mode is only for attacking groups of 3 or more ships, if the missiles do not detect 3 ships in a specific formation they will not attack anything.

I just finished this a few minutes ago and can say now this is possibly the best campaign i have experienced in DCS only rivaled by Spring Tension. The believable ROE's and procedures make even uneventful sorties exciting and the difficulty ramp up is exactly on point, Well done!

This could be pilot error but I'd add that awhile ago I had some form of game data corruption that caused my MI-8 to spin at such extreme speed that the machine would rip itself apart, no amount of rudder could correct this and the problem would even happen in air starts with 150km/h or more forward speed. Removing and reinstalling DCS solved the issue.
