ReferenceError: Error #1065: Variable {ClassName} is not defined

Question

Hi,
I am getting the following error for each of around 520
symbols in my library when I run my .fla file in Flash CS4:
ReferenceError: Error #1065: Variable {ClassName} is not
defined.
My .fla does not use a document class nor are any of my
classes using the same name. Any ideas on what the problem could
be?

Just an update here:
I copied the entire library of my fla and put it in a fresh
fla file. My original fla has nothing on the main timeline so I
figured I'd just rebuild the thing.
So, upon compiling the first time in it's new fresh file, I
get this compiler error:
, Line 1: 5005: Unknown error optimizing byte code.
Good. No longer do my symbols cause Reference Errors, I
thought to myself. After pursuing this error on the forums, I
gathered I just need to restart the flash ide. I did so, and went
to rebuild the fresh fla...
One single line in the output window:
ReferenceError: Error #1065: Variable ComponentShim is not
defined.
After wiping the tears from my eyes, I've come to post here
again in hopes someone can help me.
Here is my directory structure and names of files:
/public_html/
/webdev/
/game/
/MarbleMaze2/
/Game.as
/marblemaze.fla
/Maze.as
/MazeConstants.as
/Boards.as
marblemaze.fla has no document class specified in the
Document Class field, just a few lines of actionscript that creates
a new Game() on frame 1.
