I was playing Morrowind a few days ago on my Xbox 360, and all of a sudden, it says it isn't compatible. It has nothing to do with internet connection. Since Xbox is such [censored], it won't even connect anymore regardless of the extra $80 I payed for the adapter.

So how do I fix this problem? I was literally playing it 2 days ago.

To play Morrowind on a 360, you need to install the free update from Microsoft. The update is the one that lets you play really old games on the 360.

But! I have no idea why it would have stop working for you. Maybe something got erased from your HD??
Maybe you need to update again?

I've never heard of this problem before. It should always work after the update.
