A couple of changes were needed. The program database option for the debug build needed to be changed and the .rc file needed a line changed. I also added a 64 bit build configuration.
The following link contains the fixes for the Ninjam Loop example.

However, as I suspected, the plugin actually doesn't work anymore, probably because the server it is looking for no longer exists. (You can find and run the action the plugin adds in Reaper, but it will display an error instead of fetching and inserting the audio loop.)
I'll try to find the example plugin I did myself...
