If anyone would like to know how to fix this, I discovered the answer.
I have no idea what IPv6 is and I care not, but apparently now, all of a sudden, Apple makes iTunes talk to Airport Express units using IPv6. However, it didnt bother to make the Airport Express units expect this first, so iTunes can see the Airport Express, but it cant talk to it.
Anyway, I found that you have to manually go into your Mac settings (scary stuff if you are a non technical person like me) and turn off IPv6.
To do this, go to "Finder > Go > Utilities > Terminal"
type
networksetup -setv6off Wi-Fi (hit enter)
Then type
networksetup -setv6off Ethernet (hit enter)
and magically your iTunes will talk to your Airport Express units again.
I presume at some point we will have to undo this as technology moves on and everything uses IPv6, so when that happens go into Terminal again and type
networksetup -setv6automatic Wi-Fi (hit enter)
Then type
networksetup -setv6automatic (hit enter)
Thanks Apple for that.
