Since a couple of days I noticed that my 300i can't throw countermeasures anymore pressing Z. I have to crash with every missile I got thrown...

I verified the controls are fine. I verified that in the holotable I have equiped countermeasures launchers (2 units, left and right) (I says something like "missing, replace me! in the description :S) and I verified that changing the weapons do affect the ship in the game (If I remove a gun it dissapears as it should, but if I equip countermeasure launchers it doesn't even appear in the bottom of my hud...)

Any thoughts on this? Sorry about my english if it's bad written, I'm not native.

Thanks in advance.

EDIT: I reinstalled the game and tried to remove USER folder and all of these things. None worked.
