Guild of Writers

I have install Gehn Shard
When I start it, all is going well until I press on 'Explore Uru'
Then appeared a window saying : Unable to create file.dat/AvatarCustomisation.fni
and another window appear saying : contact the developer to submit this serious error
I dont know what to do .

Thank you for helping me.

Please be sure to fully update your MOULa installation before installing Gehn. The server relies on files we can't distribute which you must acquire directly from Cyan.

Shorah!

Thank you Deledrius.
My Moula is update.
I login with with my Administrator right and it work.
I think that I forget to log like Administrator!
