I had some issues updating my Xbox (the latest S model) with the mid-July dashboard update, but after I cleared my cache on my internal hard-drive, the update was able to download successfully.
But now I have some other issues, specifically with two games. With Assassin's Creed 2 (the Games On Demand version), now when I download the 3MB update, the game says that it is unable to play and to please try downloading again. This has happened every time I try to apply the update. However, the game is clearly starting when the update prompt pops up (the Ubisoft logo movie is playing in the background).
My second problem is with the Trial Version of Bastion. The game downloads and installs successfully, but as soon as the Warner Brothers logo and Supergiant Games logo appear, the game goes to black and then goes straight back to the dashboard. I don't even receive a message of something going wrong. I have downloaded the demo several times, keep clearing my cache, and I'm still getting the same problem. This concerns me because I feel concerned that even if I buy the game, this will happen and I will not be able to play it.
I've been considering transferring my content to an external drive, formatting the hard-drive, and re-setting up my Xbox just to see if maybe my problem is running deeper than I think it is.
I truly appreciate all your help and any advice you can give.
