I actually have the same issue. I got it a couple of hours ago and installed it. It seems like only certain areas won't load. (Southampton area for example) shows this error, Heathrow area does load. I verified all files and it still says the same. I did get a space error during the initial install, so my last option now is to uninstall the whole thing and reinstall it. It sucks cause it looks great, so I hope this fixes it.
