This is not the actual path you are using correct? :
Code:
c:\eqemu\quests\zonesn\
If it is, you need to replace "zonesn' with the shortname of the zone that quest is in. (and be sure to create that folder as well.)
Example.. quest is for an npc in Nexus, thus your path for ALL Nexus .pls is:
Code:
c:\eqemu\quests\nexus\
Just verify that you are using the correct shortnames for those folders in ...\quest.
