I just tried it and it worked... Are there any fields you missed on the form - they would be highlighted in red.
Also, the form requires that you log in to SAP/SCN, which I assume you are, but I thought I'd check to make sure. There is a "log in" link at the top of the form.
If neither of those things work, e-mail me directly. jason dot hinsperger at sap dot com
