Integrated Video Tutorials cannot configure if Wordpress is in subfolder

Hi Guys

I am trying to configure Integrated Video Tutorials. When I click the confirm registration button after entering my credentials the form is submitted but nothing happens. If I enter no credentials at all the same thing happens and I am not prompted for the correct details.

My Wordpress install is in a subfolder but I have configured this plenty of times in a sub folder with no problems.

Thanks

Kieran
