Error while submitting Infopath form to a SharePoint Document Library

I was getting the following error when submitting the Info path Form to a SharePoint Document library:
"An exception of type 'System.Net.WebException' occurred in Microsoft.Office.InfoPath.Server.dll but was not handled in user code

Additional information: A value in the form may be used to specify the file name. If you know the value in the form that specifies the file name, revise it and try again. Otherwise, contact the author of the form template."

1. Open form in Design Form
2. Go to Tools in menu bar
3. Select data connection

5. Click on 'Modify' button
6. Check 'Allow overwrites if file exists' check box
7. click on 'Next' button
8. Click on 'Finish' button
