Hello there Nostalrius Last two days i am trying to fix one problem... to play like normal player.
I got error all the time when i press on NPC (quest giver).
I updated video drivers, i was trying to re-install WoW. I downloaded new WoW 1.12.1 ( Not Nostalrius client, but i have Nostalrius client aswell) I readed alot in forum and did the thing what was said in support section.... but nothing nothing nothing. I google it... nothing

Any1 got any ideas? Thank you

Gonna need way, way more information if you want someone to help.

For starters, what error are you getting? Is it a WoW.exe crash error? An addon or LUA error?
What NPC are you clicking on that causes it?
What are you trying to do with the NPC: Obtain a quest? Complete a quest? Buy/sell from a vendor? etc.
What area/town/region of the world map are you in when it gives the error?
Can you reproduce the error every time guaranteed or is it random?
Have you tried clicking on the NPC with another character and if so, do you continue to get the same error?
