[Plugin: Audio Player] Weird problem with showing player on Main Page,

Ok, this is really weird.

On my site
https://electrostation.net/

there is player to previews tracks. Currently you can’t see him, but if you open some of the posts, like for example this one:

https://electrostation.net/2010/09/mojito-more-sugar-mix/

the player is there and totally working.

I have to mention that this happened by itself 6 hours ago.

I deactivated and activaed plugin.
Added that footer, header in my theme.

I mean everything was ok and now it’s not!

Please this is really urgent, so please help me!

P.S. I’ve got latest audio player version and WordPress 2.9.2.
