All of the downlaodable quests files for Drawde's database have not worked for me due to systematic syntax errors in the files and incorrect NPCID's. In order to overcome these problems i wrote a program to reprocess Quest files and correct NPCID's and a number of syntax problems.
The install is available here

This is a win32 application and requires MyODBC 3.51 and MDAC2.6.
Use this app at your own risk. It will not modify the original quest files but creates new coppies in the directory specified.
Since using this app i have finally gotten the quests working!
