Subway Vent Glitch

[Am-I-Insane]

Hi! i was looking for fix to that bug for a 3 days i found only tips to Crouch Jump and Try to combine with your view angle, but it wont work.
So after crossing the first Pit with pipes in Subway Tunnels (that one wich have an tape recorder before entering) everything cool i make use of my parkour skills but i cannot enter the exit vent. Theres something like invisible wall. As i wrote i tried to Crouch Jump for like an hour  . I tried to use noclip but it does not work too. I have a lot of problems with vents in coop the Vent covers are likely to be invisible.

My Specs :
 I3-4100M 2.50GHZ
 4GB RAM DDR3
 Intel HD 4600
 I play on 1280x720 resolution
 I have standalone Steam version of cry of fear
Sup! and sorry if i there was any language mistakes english is not my main language

Try loading an earlier save and going back there to see if the problem persists, or type this into the console "sv_gravity 50" then if it works type "sv_gravity 800" of course do "sv_cheats 1" beforehand, if the problem persists, there's something wrong with the map, or your controls.
Anyway, I had no trouble with this area, and it seems nobody else has, so either your game is corrupted or you're doing something wrong.
Sorry about the late reply, best of luck to you!
