When I attempt to play a playlist, I first see a message "loading %INFINITY".  Then after about 30 seconds, a window pops up that says "..movie contains a script that is causing the player to run slowly".  If I cancel the script, the player hangs. 

I have no problems running a concert directly from vault list.
Any suggestions?

Curt,

If your playlist has lots (over 400) songs on it, and you are on an older PC or mac, this is what may happen.

We suggest you wait for a couple of weeks and try again.  We have an updated player coming out in soon.

If that doesn't work you'll have to reduce the number of songs ni your playlist.

cheers - Mr. PC
