Sorry, I had forgotten I posted this here. I actually never hear GLADoS talk, so that looks to be the problem. When the level starts up, the music plays, the text displays in the bottom left hand corner, and then nothing at all.
I am SOOOOOO glad that this map pack was created; however, I have a small problem with the first map. I am stuck in the first room and the developer console gives this error: "Updating physics on object in hierarchy weapon_portalgun!" I think its trying to give me the portalgun, but it is not working right. Any ideas?
