Need now! Error 2038 fix

Hello, When I try to upload a big file on my site it always seems to time out and gives me a 2038 error. My site uses SWFupload to upload files. I need someone to fix this problem for me. The sooner the better. My script is open-source and free to modify in any way. The file stops uploading 5 seconds after it begins then I get the error. Look at the attached picture for a sample. Please don't bid unless you can fix it.
