Hey Agogobil,
I too was having this problem and this is how I resolved it(for my case):
The problem had to do with how my browser was handling cookies and its security/privacy settings. I am using Microsoft Internet Explorer. If this is the browser you are using the following steps may help you.
1.From IE window pull down menu, left click on "Tools".
2.Then left click on "Internet Options".
3.from the Internet Options window left click on the Tab labeled "Privacy".
4.Where it says Web Sites - To override cookie handling for individual web sites, left click on the "Edit" button.
5.Under address of web site type in :
http://www.congaplace.com then left click on "Allow"
6.Left click on "Ok"
7.Again, left click on "Ok"
What this does is that it allows your computer to receive cookies just from congaplace.com without hindering any of your other security/privacy settings.
It worked on my computer.
Hope this helps
David
