Upgraded iTunes, cant access shared libraries anymore

[esvee]

This happened twice on the same machine, so I'm positive the upgrade is what did it. I upgraded to 8, and the library I could access before has dissapeared. The vista pc its on can see mine, but I cant see the library on the vista pc.

Ideas?

On both systems, yes.

try restarting router

This happened last night. I also lost ATV connection. I was scouring threads and came across somebody suggesting restarting the router. I didn't think it would work or had anything to do win what I was doing but I did it anyway as a last resort ... And it worked.
I have a AEBS iMac Macbook and ATV on the network.
