Left 4 Dead 2 Forum

Hard Rain was the next campaign up for me. I soon found that the game would crash shortly into the campaign. I then tried to start at the Mill (2nd) map and it crashes shortly after starting it. I then tried to play Dark Carnival, a campaign I played last night - it also crashed. These are all complete dumps to the desktop, no warning or anything given. It appears to happen just before or after some hud text is displayed (hint text for instance like Manual Reload). How could this go from working perfectly last night and today to not working with NO UPDATES?! Is there some sort of cache I should try and clear? Anyone else having these issues?

System Specs:
iMac Core2Duo 2.4GHz
3GB RAM
ATI 2600HD 256MB

Triggers set (have tried without them):
-lv -novid

Yah, mine crashes a lot but tʻs about after 7 minutes or something
Another update is in order? Thank you so much for covering for VALVeʻs error
You guys rock :D

Same happens for me. There was one change though, Steam itself was updated. Besides, many windows users have the same issue...

For me "utlmemory.h (322) : Assertion Failed: IsIdxValid(i)" pops into console when l4d2 craches.

Campaign is practically impossible to play, as it crashes after 1-5 mins, but at least survival mode works just fine...

Yah, i get about 1/4 of the way through a campaign and BAM
the game stops and sounds start stuttering, then sometimes a Runtime error pops up
I forgot the number but iʻll post it if a see it again, mine doesnʻt dump me back to the desktop but i need to exit it to play it again
:(

Edit: This is the problem

Runtime Error!

What does this mean?

I can only guess... Anyways, I don't get that or anything similar. And I'm also not dumped to desktop, just l4d2 crashes, steam does not, and I can just launch the game straight again.

I get the exact same error, though it seems to happen in the same spot of the campaign every time. For example, right after exiting the boat in Swamp Fever 1.
