I have noticed this on mine whenever i switched to 4.x. sometimes i will have to shut down ej several times and re-launch before it will start winamp. (also rebooting computer). this computer is only for the jukebox so i don't have much running other than ej. now if i start winamp and then launch ej it will play.

any ideas on what i can do?

win xp pro sp2
p4 3ghz 1.5gb ram

thanks.

Start Winamp first then start eJukebox and it should load winamp on eJukebox startup the next time.

Also make sure Winamp is not froze first - if it is do a CTRL+ALT+DEL and end the winamp.exe process.
