Register Event Error

[Carbon8Jim]

When trying to register the event PARTY_MEMBERS_CHANGED

to fix this, i updated in addon.lua
Line 91: Prat.IsClassic = (_G.WOW_PROJECT_ID == _G.WOW_PROJECT_CLASSIC) or (WOW_PROJECT_ID == WOW_PROJECT_BURNING_CRUSADE_CLASSIC)

playernames.lua
Line 1131:
if not Prat.IsClassic then
self:RegisterEvent("PARTY_MEMBERS_CHANGED", "updateParty")
end

The PARTY_MEMBERS_CHANGED event has been removed with TBC Prepatch. The alternative calls GROUP_ROSTER_UPDATE and GROUP_JOINED GROUP_LEFT are already registered (hence why Prat continues to work).
