Macro stopped working after addon installation

[Deathsting1991]

Hi,

My macro stopped working after the installation of this addon.
Even after the deinstallaion, it stil doesn't work.
What can I do to fix this?

The macro reads:

/run local i,x=1,0 while UnitBuff("player",i) do if UnitBuff("player",i)=="Interface\Icons\Ability_Warrior_BattleShout" then x=1 end i=i+1 end if x==0 then CastSpellByName("Battle Shout")end
