When I log on my elemental Shaman LUA errors are rising immediately, saying that in Cooldown.lua:460 arithmetics are done with duration, which is a nil value.
To get a trace of the cause I added
cdduration = cd.duration if not cdduration then cdduration=0 end
and changed the access in 460 from cd.duration to cdduration. I know, this will only fix the symtoms, not the cause.
Reloading the UI after this a vast list of spells, which are now unknown is posted into the chat window (which I guess is the cause of the problem).

Element shaman script need a level 100 shaman, which I don't have. Can somebody tell me if it works?
