OS: Windows XP SP2 (32-bit)

I guess I should be a little more clear at where this is happening. Initially I tried to do this in a simple client test application, but that was failing so I tried to do this call within the actual exe. It throws these errors in both cases.

Possibly I need to start over with my project. I created this project as a standard ATL server and added simple ATL com objects through the wizard within Visual Studio 2005. After I was done I manually modified some of the GUID's. I assume this is where my problem lies, but I wasn't sure.

Thanks for your help!
