HL1 Annoying showstopper glitch

[burnzie]

Hmm ok I'm playing through HL1 again and im on Zen (interlopper) and i defeat the garg and get past the tenticals and through the teleporter. I get to this room with barrels and vorts with conveyer belts and a lift... I get to the conveyers and get to the one without the forcefeild drop down... it loads breifly and i fall into a pool, climb out and these invisible vorts shoot at me through walls... the map is incomplete and i either fall down into oblivion in places or get stuck on invisible barriers and the vorts shoot me to death. I've tried loading again... even completed the level again. Ive checked the integrity of the files and it doesnt say anything (is it supoded to say ok or something?) and just goes back to the games menu.

Anyone got any ideas?

There should be a progress bar of some kind when you check the integrity of the game cache, also try defragging the files (theres an option to do that somewhere there). Are you using any cheats or mods while playing?

 

[burnzie]

Nope im not... the progress bar comes up but no progress is shown and it vanishes 10 seconds later. I'll try and defrag when i can be bothered to play it next...

If you're out of luck completely, type sv_cheats 1 in the previous level (HL1 only activates server variables after mapchange) and use noclip to see if you shouldn't be somewhere else.
