Hi all!

After months, my "music PC" is back online and I was anxious to update my last.fm account.

Unluckily, I get the following error:

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">;

The same foobar2000 (v 0.8.3) and scrobbler (1.2.4) used to work before. The only thing that changed is that I am now using Vodafone Mobile Broadband as a connection, no landline.

Could that be the problem? If yes, would more up to date versions of foobar/the scrobbler solve the problem? Can I easily export/replicate my current tabs and playlist on another foobar?

Thanks a lot for all the help!
