I make it on a other way:
1. Create on the normal page a Account on Testserver 2
2. Create a BigPoint Account.
3. Connect the Darkorbit Account to the BigPoint account.
4. Start the game from your BigPoint account. (right click on the 'Start Game' Button on Big Point.com and copy the link)
5. Paste the link in a new tab and try it with this link until you get redirected to internalCompanyChoose
But thanks for your method!
