[Plugin: Global Translator PRO] users don’t stay logged in on translated pages?

Well this is the first time i paid for a plugin but support is laking cause i didn’t pay 60$ extra for some support? So I hope i can ask the questions here.

When a page is translated/cached and I visit one of the translated pages it doesn’t keep me logged in.

A good example:
http://www.cell-systems.net/2010/03/29/left-4-dead-2-dlc-wont-release-this-month-will-cost-560-ms-points/

Now click on the DUTCH flag and it will take you to the translated page, but it doesn’t keep me logged in? What am I doing wrong here? Is it something in my .htaccess file that needs to be changed/added?

I hope someone can help me with this.

Kind regards.
