the details which u have used to get onto the forum are your login details for the site, so use them. As Supernatural is a VIP Show you will need to make a donation to watch them on the vip tv site. Otherwise you can use the
www.tv-video.net.
You can make a donation via paypal. There are links direct from the homepage for vip.tv-video and you just fill in the details, and then you will recieve an email with codes on it which u enter in the box where u login on the homepage, there is a little bit under the username which has logout, message and vip card, click on the vip card and follw the instructons to put in the codes from your email. It can take up to 24 hours for the codes to come through but they can be quick...
Hope that helps you
