Did anything export? Do you show materials? Try a zoom out. Please realize that the plug-in update is just an update to your existing eXchange Plug-in. I told Maxon people would be confused by the download page.
It still works, but you cannot update the geometry - it is crippled without the full program
edit: Wait a minute = that is Maxonform which is also a complete program, these plug-ins are updaters only. It is not free.
