After trying all of this I finally had the idea of changing the case of my username to all lower case. And wow! It worked! I just had a small database error (easy to fix) and presto the world.exe was running just like it should.
So it seems it was a username/password problem but the solution was easier than any of us where thinking. (Lol, isn't that often the case).
I wanted to thank all of you who helped and tried to help. I do appreciate it even if it doesn't get me anywhere. In this case it mostly helped to get me thinking in the right direction...
Edit - lol, now I'm getting that annoying 1017 error. Time to fix that too.

Can't tell I'm happy about this, can you? :P :lol:
