I cannot find an Upload field on your jotform http://www.jotform.us/form/50305388509154
so I am not sure how you are suppose to upload document on your form submission.
You need to add first a file Upload field on the form.
then retry testing with upload submission again. It should work even on IE browser.
Please let us know if issue persist.
