Why did you guys change the format of the player? Everything was fine and I didn't have to download or install any programs in order to enjoy the music. I listen at work and my work won't allow me to install on this computer. Is there any way that I can listen to this great music in  the old format.

Ditto. 

I have Adobe Flash player 8 here at work and it won't play the concerts.  I'm missing some great shows!
