8.40 Map loading problem!

[hellyea]

Hey guys, title says all..
I tried to made an own map - i did all right - with tempel position etc. but when i start the server it makes an "error"

I used the Forgotten server and RME Map Editor 1.1.5

[20/02/2009 22:19:05] > Map descriptions:
[20/02/2009 22:19:05] Saved with Remere's Map Editor 1.1.5
[20/02/2009 22:19:05] No map description available.
[20/02/2009 22:19:05] > FATAL: OTBM Loader - Unknown map node.

***EDIT***
I got it.. When i make - Edit Town, and i delete my "Town Name" and save and start it again it works.. but how can i fix it ?

What is it? can someone tell me ?
Thanks
greetings Hellyea
