I have a big problem which has emerged recently when running my Portal 2 maps. When I compile my map, everything is ok, no leaks, so Portal 2 starts and begins to load my map. It gets to the sixth little dot on the loading bar and stops. The spinning circle stops too. This happens on every custom map I load straight out of Hammer. I tried just starting Portal 2 normally, and then putting in the commands to load my map, but everytime, for every custom map, it stops loading at exactly the same point every time.

verify your game cache?

Make sure that the names of your maps are not to long. Try to keep them less than 16 characters.

Thanks for the help. I definitely think that the name of the map I was running was too long, although other maps didn't work either. Anyway, for some reason all my maps work again, except for the one with the long name. That is ok though, because I just renamed it and ta-dah! It works

Nice, good to see the problem is solved ^^_
