Crysis extraction point HELP!!!!

Thank you for any one that can help me with this!
The problem that Im having is the game seems to be bugged. For example I am
on level Relic and when Im at the extraction point and I kill all the guys
in nanosuits nothing happens. The VTOL never lands! Im stuck and cannot go
to the next level. I have tried replaying the game back to the last saved
point so many times I have lost count. I also tried replaying the whole
entire level again but that does not work either.Also I killed every enemy
on the map and still the game want progress. I paid $40.00 for this game
and now I cant play it because of this problem. I have in stalled all the
three patches for this game 1.1, 1.2, 1.2.1 Please help me!
Thank you so much for any help.

I had that problem too, means that there are STILL enemies running around the graveyard area, you'll have to find them all.
