Restart your system!

A friend of mine had exactly the same problem. He tried all the described options but nothing seemed to work. After many studies, also of Microsoft's description, he concluded to restart the system. It worked!!

It seems that the operating system does not in all cases refresh the list of registered event sources. Only after a restart you can be sure the event sources are registered properly.
