Whenever I do a test with this script it continually fails at the upload attempt and gives the error IO #2038
The thing I can say for sure is it never even gets to the backend script of 'Upload.ashx'
Which that tells me it is a problem is with the script somehow. Now I am doing this with localhost on my test machine.

Are you using SSL? It could be a problem with your certificates. Check if your certificate is valid for the domain.
