Is scrobbling possible with Vodafone Mobile Broadband?

Hi!

I'm Vodafone Mobile Broadband for my desktop PC and my laptop. The scrobbler of my MP3 player foobar 0.8.3 seems to be able to "handshake", but when it comes to submit the tracks played I get the following

INFO (foo_audioscrobbler) : Submitting cache...
INFO (foo_audioscrobbler) : Submission failed: html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">;

Any ways around this? The scrobbler is version 1.2.4...
