Hi Seter, i have already gave you more details in PM.
Please tell me if there is any need of more info i will be glad to provide.
Thank you very much
PD:For the ppl interested:
It seems that creating two scenes with the Arx map of the adon "GM Campaign Maps - Arx, Fort Joy, Reapers Coast (Driftwood) Nameless Island" make the game crash if you try to load that map after creating two of them.
