ioError #2038: Mac issue?

So I’m developing a flash application in AS3. What I have is a gallery with a list of images and I have a button at the bottom of it to allow a user to upload their own image.

When I begin the upload, all is well on a PC. However, on a Mac (OSX 10.4 Tiger is what I run), I get a Flash ioError #2038. Also, side note, the server response is 503. I’ve tried Flash Player 9 (three different versions) and 10, and it still does it. :suppose_maybe:

I’ve been searching the past 2 days on a solution to this, and am yet to come up with one. Does anyone have any ideas as to why this happens?

Cheers! :beer:
