Animation problem

Hello!

Dont know why, but my animation doesn't work, or doesn't show. I made animation in Blender for my gun ( reload, bobbing, fire, start of fire, end of fire, switch weapon etc. ) Now i imported in .blend file, in .fbx and colladae, not$$anonymous$$ng works. FBX imports everyt$$anonymous$$ng, even animations. But i don't know where to view, where to set the animations. ( It shows a video, 10 second, from 1. to 250. keyframe, but the weapon is still stands and does not$$anonymous$$ng )

Thank you, and sorry for my bad english!
