Hi i have completed the level after u finish the tentacle creature i head down the ladders and it pops up saying loading so i sit here and wait then i got error message saying hl2 has stopped responding. so i click close program i tried that level again and no hope kept crashing. i restarted the map i did all sorts to try and get it to work. but no hope so i hope this can help for you all and another thing if i can ask if you send update out or patch were do we get it or will that pop up on the forums. i would look for crash reports but i dont know were they are so if some one tell me were abouts they are i give them to you.
Attach the minidump file in another post, so that hopefully the developers will have a look at it.
Ok thanks Giazzo for that i have found them. theres few but never taking the chance ill put them all in. here they are.

Ok heres a new update for all of you trying to pass the level on blast bit. when you walk down the ladder and it says loading and crashes but i have seem to fixed it. its not really fix but it works if your resolution is higher then 1280x720 it crashes but soon you put your resolution to 1280x720 it works fine for me it did for me i hope this helps. this is temporary till the developers fix it but im so happy i can continue with the game. heres picture of it not great as i need to re install fraps but it will do ok bare with me i just tried to continue and its just died i will see witch resolution to confirm to pass that level now

ohh right i thought help few dam ohh well looks like have to wait till the developers fix the issue.
At least it is now known that messing with quality settings and screen resolution allows to workaround the problem for some people. My suggestion to people who are still struggling with this is to keep on trying with different quality and resolutions.
What to change at a first place: HDA None/Full, shadow details low/middle/high, models detail low/middle/high, texture detail low/middle/high, water details l/m/h/ and so on.
Yep, it’s a lot of trial and efforts but chances are in the end you would be able to continue playing.
I know several supposedly full-screen effects are actually locked at a 4x3 aspect ratio. I made a thread about the shotgun not shading past a line where a 4x3 rectangle would end on my 16x9 monitor, so I’m thinking this has something to do with it.
I’d say, if you’re messing with resolutions, try different aspect ratios. Specifically, see if it works at 4x3
yea trying that may help i remember right it was 4x3 but i messed with the aspect ratio and i seem to get it working so keep trying peeps. thats how got mine working.
