Are you sure that you registered the right map? Because i had the same problem, ago a few months. I mean that i set a false map into the quest.
Edit: Here is a tutorial. Maybe it helps you two.
Tutorial in English:
Moin...
you go in the game folder of ch1
ee CONFIG
search for the MAP ALLOWS 110 and 111, and delete them.
then go in the ch99 folder, where should run OX...
and sign in both map index in there.
Reboot your Server
and Voila! Guildwar works....
