I've got Winamp 2.91 set as my default mp3 player. I've set WMP as my default wav player and also tried converting the wav files that thread suggests to mp3 then back again. It didn't work.

The crashes don't occur when I get a harvest message, they've only happened directly after the throne room doors slide open and when the heir coming of age window pops up.

Thanks for the help so far guys.
