Unable to Add Album Details to mp3 file

[SerFaren]

So, I created a song and I want to add the Artist (Me), Album name, Track name, etc., and yet, it won't let me. Everytime I try to type something into the boxes, it doesn't allow it and doesn't save it.

I'm running Xubuntu 11.04, but I figure this COULD be and issue for others, as well.

Any help would be appreciated.

Thanks!
