Create a new Database called MirWorldDB, then import the Sql files out of the DB folder.
For those that dont know, open up SQL Server Enterprise Manager, goto Tools menu, then SQl Query Analyser, then goto File menu and select Open. choose the Sql Tables from out of the DB folder then click the Run button. Repeat this for all of the tables.
To create an account so you can log into the game, go into SQL Server Manager again and select the MirWorldDB you created and then double click the Table icon. You should now see the tables you imported, right click on the TBL_Account icon and select Open Table, Return All Rows. Once you have entered the details right click and Select Run.
