can't reload Thread

Hello, every seems to working OK, However I can't reload and the weapon doesn't recognize the ammo in the inventory. Any suggestions would be much appreciated.

further, the "r" doesn't work on any weapon I've acquired. just dips the weapon. I've got ammo in the inventory. But it shows zero in the ammo on the screen. I've checked the "user LTX" file and it confirms the r is the reload. Come on surly some one knows how to help?
