Sounds like a possible DNS issue with your network set-up - the player may be unable to find specific BD-Live servers because the domain names are not resolving properly. Here's a post on how to set the network settings manually. Try that and see if it helps. If it does, then it is most likely a compatibility issue or problem with your specific router or network switch.
Why doesn't BD-Live work on my Blu-ray Player?
Hope it helps.
