Disappearing Crates

All maps.....Highest video settings....Win 7 64 Nvidia SLI


I cannot drop crates from a logi. All crates disappear. They are not there. Kits not obtainable or building allowed.

Crate drop reading goes from two to zero with one click.

Reloaded ENTIRE GAME AND PATCHES several times. Graphics ( several versions) Same problem.

Everything else within the game is normal.

Please advise.:-?
