My Amarok acts weird with Last.fm

I can use the Global Tag Radios Perfectly.

But whenever I try to use the Personal, Neeighbor or Custom Radio I get this mssg

"This item is not available for streaming"

If I keep trying Amarok crashes.

I'm Using Kubuntu Feisty, with 1.4.5 with KDE 3.5.6

Any ideas?

Custom radio no longer works due to a recent change in the protocol. Will be fixed in 1.4.6.
