Hello! Just reporting.... tks for this addon!

Hello!
Could you please post a lua error you get? If you don't see any errors, try enter this command to chat: /console scriptErrors 1

Hi! I tried it again... at first, it kept not showing with no errors. I typed the command you suggested... nothing showed. But then I reported another player, got an error msg and tried again... the list appeared! So I closed the game and did it all ove again and everything seems to be normal. One thing I noticed is that when it didn't work, the button "click to select spell" as grey... now it's red. Well... everything seems to be working now! TY!

The button "click to select spell" is displayed grey if you have enabled test mode, or if you just opened NC options window and spell cache is not build yet.
