A widget on my wordpress site has stopped working... need it fixed!

My website and daughter website use a plugin, that takes the most recent audio post from my tumblr and displays it on my wordpress page...

The information displayed is the album artwork and the tumblr music player and whatever blurb we have written about the song...

It has worked perfectly until today, now if you are viewing the widget with Firefox you can't see the player, the artwork or the blurb... If you look at the webpage on Safari, the player loads as does the blurb but there is no artwork ... I think the problem is with tumblr

website - www.fluxmusic.net (widget on the bottom left)

daughter website - http://words.fluxmusic.net

tumblr - www.totd.fluxmusic.net

Please find attached, a screen shot of how the player used to look...

and how the player looks in the website
