On what computer operating system is your Premiere Elements 11 running?
In what workspace are you working - Expert or Quick? Whichever one, have you tried addressing the issue
by going to the other workspace temporarily and trying to resolve the issue there?
Have you added any narration to this project using the Premiere Elements 11 Narration Tool?
What is the source of these .mp3 files?
What is the size of the project when the soundtrack content is not manageable?
Let us start here and then decide what next.
Thanks.
