Hang on, hang on, what are you trying to import exactly?
Lets start from the start and maybe we can get somewhere
Ive downloaded the file from the front page, the repack, if you are trying to install 'Chrispee Repack Gates of Zul aman.sql' you should make a brand new database in Navicat for it, dont copy it over what you already have, make a new database on your current connection called 'chrispee' or something, and execute the batch file 'Chrispee Repack Gates of Zul aman.sql'
Im importing it right now, Ill give you more advice after its done.
OK - the repack 'Chrispee Repack Gates of Zul aman.sql' has the accounts table built in, so you just need to point the world server, and the character server to the same database you make with Navicat.
To login with a character for the repack, there is already a GM account made for this repack, username and password is 'admin'
Hope this helps.
