My gmap > converting > won't work

[WanDaMan]

My gmap won't work..
I make it so I can open in word pad and I just added more levels and changed the size of it by adding the two together but I come out with this (in the zip, the map).
Why?, I wanted to add alot more levels on to my server and it just wont.. Any help would be appreaciated..

I tried converting
wworld.gmap + world1.gmap

My outcome is
world.gmap

But it turns out like the map

^in the zip
