I have the same issue, I used to use media connect and that worked perfectly, I then used WMP 11 with XP again no problems, I then moved to Vista which worked fine till I started using orb, now I can't get WMP to work, or more to the point I can't get my 360 to see my PC. After some trawling the Internet last night I found this

Below is an extract which I think will sort my problem, however, I have not tried this yet and you should always be careful when making changes to your registry. I'll let you know if it worked later today.
Q. I used Windows Media Connect running on Windows XP and then upgraded to Windows Vista. Now media sharing stopped working. What can I do?
A. If you previously used Windows Media Connect in Windows XP to share music before upgrading to Windows Vista and then you try to share music using Windows Media Player 11 for Windows Vista, media sharing in the Player does not start automatically. If you try to turn on media sharing in Windows Media Player 11, clicking the OK button in the Media Sharing dialog box does not enable media sharing. This issue can occur if the computer has multiple user accounts.
To work around this issue, perform the following two procedures. The first procedure provides the steps to manually remove the Windows registry key where the permissions are not set correctly. The second procedure provides the steps to set up media sharing in Windows Media Player 11 for Windows Vista.
To remove the Windows registry subkey that does not have the permissions set correctly
1.
Log on to Windows using the user account that you used when you upgraded to Windows Vista.
2.
Click Start.
3.
In the Start Search box, type regedit.exe, and then click OK.
4.
In Windows Registry Editor, navigate to the following registry key where the Security ID is a string of alphanumeric characters in the navigation tree on the left side:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\ Preferences\HME\<Security ID>
5.
In the registry tree on the left, with the Security ID subkey selected, on the Edit menu, click Delete.
If you do not have permission to delete the selected Security ID subkey, when you try to open the subkey, an Error Opening Key dialog box displays with an “Access is denied” message. You can then select the next Security ID subkey in the registry tree, and then try to delete that Security ID subkey.
6.
Repeat steps 4 and 5 for each Security ID that you have permission to delete.
7.
On the File menu, click Exit.
8.
Click Start, point to the arrow next to the Lock button, and then click Log Off.
9.
Log on to Windows using the affected user account (the Security ID subkey or subkeys that you deleted).
10.
Go to the next set of procedures to set up media sharing in Windows Media Player 11 for Windows Vista.
Note
Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on your computer.
To set up media sharing in Windows Media Player 11 for Windows Vista

Start Windows Media Player 11.
2.
In Windows Media Player 11, click the arrow below the Library tab, and then click Media Sharing.
3.
In the Media Sharing dialog box, select the Share my media check box, and then click OK.

It might take a little bit of time for your digital media device to appear in the list of devices.
