when i try to play a demo it freezes at the loading screen after its done loading. I've tried all of the fixes but it just doesnt work. HELP PLEASE!!!!

When the demo map loads,type in the ingame-console "/demoback 1"

Also nice double post viewtopic.php?f=17&t=19595&p=153159#p153159

i tried that but it didn't work. I also found something that might help. When I use task manager to quit the game, the console out of the game says something like missing ambient sound mp_complex. I checked my other demos and sure enough the demos that were recorded on the dlc maps dont work but the ones recorded on the regular maps work. Any suggestions?

Also I accidentally posted the thing in the mods section XD

Verify cache integrity of the game via Steam because it seems like you have a corrupted .iwd file..
