Flash CS4 won't open previously working fla file!

oh, guys I’m so bummed

I try to open my file and I get this error:

The following JavaScript error(s) occurred:

In file “”/Users/Jeremy/Library/Application Support/Adobe/Flash CS4/en/Configuration/Javascript/ObjectFindAndSelect.jsfl"":
Cannot find file file:////Users/Jeremy/Documents/creative/meatheadz/mouse story/mouse.fla.

I was really psyched about this work, if it’s lost, it’ll be a real drag!.

I really don’t know what to do!
any hints?
