COM Exception 8001010d

I'm using WM_COPYDATA to send a string from one program to an other.
In the receiving program I have to override WndProc, see code below. In
WndProc I need to call a button_click function that does a call on a COM
server.

This results in a COMException: 8001010d, See below for full exception.

According to some threads I have found using Google, the problem is that
WndProc is using COM and therefore I can't call a COM server from WndProc.

Anyone that has an idea on how to solve this?
