RTR Competition

[Dutch_guy]

Imorthorn , try the following:

go to your RTW directory file , then go to data, world, maps, base ( delete the map.rwm file )
now go back to maps , now select campaign, RTR , the select the same file as before and also delete this file.

you should have deleted 2 ( the same ) files.
MP should work now.

PS this is exactly the same as Nihilist said
and beware , you will have to delete those files every time you want to play a MP battle
