Automation server problem (Aut. that merges pdf files)

Hello!
I have tried to create a automation server using a tutorial i found here
http://www.gekko-software.nl/DotNet/Art03.htm

The trick here was to tick of the checkbox to register for COM.

I have tried this and saved 3 reports to PDF. Then i run the automation server on the Server itself. The result is that the Role based client disconnects and asks if it wants to reconnect.
The server is a x64 Windows 2008 server running a 3 tier arch. I have also registered the processor (in visual studio) for the automation server to be x64. The client itself is running on a x86 computer. I have an idea that the problem lies somewhere around the x64 and x86 compatibility.
Has anyone else been through this problem?

Here are some relevant screencaps and some code.
