Hi !  I have a bit of a problem. I went back to my FSX program after several months of not flying and I attempted to open the weapons panel and discovered the control keys no longer work. I can move the controls manually with my pc mouse but the weapon panel is not activated.It shows zero rounds left and does not engage radar lock when in close proximity to another plane.  I hope there is a quick and easyfix to my problem; Any help will be apreciated.
