Last.fm on XBMC ppc

Hello,

I have XBMC running just fine on my old PowerMac G4, playing files from the network and also streaming through the Sky.fm music add-on.

What's not working though is Last.fm. I do have a subscription, so that should not be the problem, and I can play my Last.fm library from another computer with the latest XBMC. On the PowerMac however, I can only browse tags and similar things, playing my Last.fm library, or anything else for that matter, does not work.

I am wondering now, is the Last.fm plugin broken for the PPC version of XBMC? I am running the latest one, which is xbmc-11.0-ppc.

Thanks for any help...
