Never mind, it's been solved.
It was Port 4343.:)

How do i know what that might be?

Based on your screenshots, I believe @Mirfster was correct and the 'wakemeonlan' program is complaining about a missing port number.

You'll have to experiment and do some research to find out what works on your system.

EDIT: Never mind, I see that you've figured it out!
