Yes, they do need to figure this out as I am sure it will have an effect on their overall sales as long as the issue persists.

As someone else pointed out, this is probably a lingering effect of the initial DRM groundwork where all games were fully installed from disc. It was no doubt built from the ground up into the OS. A fix might take a while.
