Cannot Upload

I recently upgraded from Server 2003 to Server 2008 and now the upload does not work.
I have all of the necessary items in the web.config setup correctly and am using asp.net impersonation.
(Basically, it is setup just like it used to be and it worked perfectly before)

When the upload mode is set to "Flash"
 - The progress bar indicates that it completed but the file is not there.
 - There is never an error
 - There is never anything in the Windows Logs that indicate an error

When the upload mode is set to "Browser"
 - The progress bar sits on 0% and it never changes
 - There is never an error
 - There is never anything in the Windows Logs that indicate an error

I have triple checked all of my security settings...any ideas?

Edit:
I am using version 1.6 and I have paid for a license.

Hi,
Did you include the following settings in your web.config for IIS 7 integrated mode?

        <system.webServer>
          <modules>
            <add name="GleamTech.Web.FileTransfer.UploadHttpModule" type="GleamTech.Web.FileTransfer.UploadHttpModule, GleamTech.Web.FileTransfer" preCondition="managedHandler"/>
          </modules>
          <validation validateIntegratedModeConfiguration="false" />
          <security>
            <requestFiltering>
              <requestLimits maxAllowedContentLength="2140708864"/>
            </requestFiltering>
          </security>
        </system.webServer>

That was it!!!!  Thank you so much :)
