I have another problem in the same mission, and i am also playing it on pc. However in the beginning of the mission, after you sniped some enemies from a helicopter, after the helicopter landed, i was unable to move and jump. I could sprint, but only the animation would come, but am still not able to move. I have tried to restart the mission, and re-installing the game. I have experienced the same glitch in mw3 multiplayer on ps3. Anyone know what i should do? (And sorry, Peterthefish, for not being able to answer your question.)
I don't think Peterthefish minds, his post is three years old
