Can you try making a very simple upload page with just a file field and a submit button? Set the upload location to be a folder directly in the root of the folder.
I just tested this using build 1.1.3 using both ASP VB and ASP JS and they both upload the files correctly. I used Any form post as the trigger.
Make sure you have permissions set to allow everything for the everyone user on the upload folder.
Are you getting any errors when you are uploading or is it just not uploading the file?
