Uploading Files Using Flex & PHP

I'm having problems getting files onto my server using adobe flex and php.

As it stands my application will prompt the user to select a file, when the user selects the file it displays the following error,
Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
      at app/upload()
      at app/___Button1_click()

The flex app links back to an upload.php page which handles the file and transfer it to the server, the odd thing is that it works fine locally but not online, I have changed the permisson on the folders but still no joy. I'm wondering if anyone could shed any light or provide a link to a flex file upload tutorial that works.

Thank you
