I configured uploads for images, videos, documents, and templates to work on the trial. After expiration of the trial I purchased an IP license.  I am now getting an error on my development site after installation of the license file.

I did not make further configuration changes after initially getting uploads to work.

To double check I have reviewed the .config file and they do still point to the directories I created under the root. 

I have not changed the names or moved the designated directories for the uploads and the file permissions for those folders still properly set  IUSR.

The site I am using is a dev site which uses the same IP as my production but uses a specific port number. Could this port number be the problem? 

Solved: File upload does not work if you use  Request.Form anywhere on your asp code. This seems to be a bug. Passing parameters via querystring instead.
