Huh, I was literally just about to report on this Exostra Run crash, good thing I found this thread.
I knew that the problem only occurred in the European (aka PAL) copy, but I didn't realize it was because of the Urban Paks! (The music in the Urban Paks isn't really that fitting with WipEout, anyway.)

I'll be sure to test the game without the Urban Paks installed.
