A lil late for help but I'm restless and can't sleep.
As noted above, you need to repair your database, it's a mess and not current
Second, try switching from "localhost" to 127.0.0.1 and see if that helps you connect.
Thirdly, since you're doing a LAN Server, try changing your LoginServer.ini to:
[LoginServer]
loginserver=127.0.0.1
loginport=5999
worldname=Your Server Here
worldaddress=127.0.0.1
locked=false
** Notice the port change number **
I hope that helps. Good luck!
