The problem is with drone controls. Help, I beg you! (Tom Clancy's Ghost Recon: Future Soldier)

I downloaded the most corrected version, all versions of the patch up to 1.5v are installed.
The problem is this: Every time I control the drone, in general, all the actions with the drone work except, to lower it and raise it (just a little but rise back, I press down and the mouse wheel jerks down, it vibrates a little noticeably) and land on the ground and magnetic the impulse also does not work (((
Help, I beg this does not allow me to complete the mission "Tiger Dust"
