it seems not all of the sql's are correct. At least it did'nt work for me.
Here's what I did.
(I have all sql files in my mysql\bin directory: db.sql, items.sql and the sqls from the DB addon)
I suggest you delete the eq database with the winadmin programm you created it with and in the same step create a new one.
Then start mysql.exe from the command line.
> use eq
> source db.sql;
> delete from items;
> source hq-items-3.6.sql;
> source hq-spawns-3.6.sql;
> source hq-books-3.6.sql;
the magelo items do not work for me. Maybe someone knows if theres some kind of problem with it.... I am a newbie myself
Still, I got the spawns working that way and there are only some high lvl items missing (most likely those are part of the magelo DB)
hope that helps
