Airport Express drive will not show up on Share list.

All my media is stored on a hard drive that is connected to my Airport Express. My Mac can see it, and I also used to run XBMC on the ATV2 and it could find it easily. When trying to use the media player function of aTV Flash, it refuses to show up in the list of shares. I’ve spent the best part of this afternoon searching for the answer but I cannot get this to work. How do I get the drive attached to my AE to show under the Shares? Thanks for your help.

Bump. I really need to know why this isn’t working

Same issue - but with a NAS - can find and play movies from XMBC but media player will not mount

 

Anyone have this issue (working fine before update)
