It notes a new issue due to a Microsoft update this week.
Sorry about creating another 360 media center thread. I couldn't find one that had my exact problem. I am running my 360 through my desktop running Vista for Xbox live. I was able to access Xbox Live and my media. Now, the problem is that I can't access my media anymore, but my xbox live is still working. When I test my media connection it can't find the computer, even though it did before. I've turned off windows firewall and enabled sharing, just like it was before.
The only thing that I can think of that did this is when I either
a) rebooted my computer or
b) installed TVersity and it screwed everything up (it is now uninstalled)
The weird thing is is that I can connect through Windows Media Center briefly, but as soon as I go back to the dashboard I can't access videos or media center again.
I've gone through everything and can't figure it out.
