Nostalrius Begins - Quality wow vanilla realm (1.12)

when ever i try to save the text to set realmlist logon.Nostalrius.org and try to save the note the save fails and it asks me to check and see if the file is open in another program please help

make sure that WOW is not running when editing the document.
also best solution is to cut the realmlist.wtf and paste it on the desktop, edit from there and cut/paste it back.
if it still gives the message it is locked, restart the PC and try again.

Also, check you have permissions to alter the file.

If you installed game as Administrator, you will also need Administrator privileges to alter the file.

And how do you give urself admin to save the file? i cant save the file it says i have no acess..

Can someone please explain how i get access to change the realmlist i am such a noob (i might have installed as admin idk)

Thx
