HOW do i install an arena?

This is something for Icetiger1067 but I assume you cannot just use the German arena for Phoenix.

exildaot the arena called Welli is an international arena, so you can use it only for international teams. if you want to use the Welli you have to rename the areanWEL.big-file in to the arena you want to change, maybe in arenaDEL.big to use as standard arena for DEL.

The same procedure for NHL-arenas, e.g. arenaANA.big is the arena-file for Anaheim. Just look in NHLView for the abbreviation, this three letters are part of arenas´name.
