iTunes & AirTunes Error -15000
"An error occurred while connecting to the remote speaker "airport express". An unknown error occurred (-15000)."
I'm guessing that one of the iTunes upgrades I installed has messed it up, but I don't know which one. I know for sure that it worked with iTunes 7.
I am using the following equipment & versions:
Macbook Pro OS X 10.5.7
iTunes 8.2.1
AirPort Express Firmware 7.4.2
I have already searched the support forum and tried the following without success:
http://support.apple.com/kb/TS2278 - my IPv6 and firewall are set correctly
http://support.apple.com/kb/TS2277 - am already using the latest AiPort Express firmawre
Anyone have ideas or suggestions for fixing this?
Mac OS X (10.5.7)
