In last Seow mission after take off i couldn't retract my landing gears!

(resolved by diving and ripping them off... but resulted with a torn plane much slower than my wingman!!!)

here's why!!!!

so when i press G to retract landing gears i lower power to 20%....

keys now are still fucked up!!!

power 40% and 50% are also fucked up...

anybody knows how to restore keys without reinstalling everything???
