[Help] update server and questions

Hey guy's have two problems i'd like to solve today . Problem one I've been looking for a way to update my rev without haveing to delete my character information for a while now, everytime i try someones "method" i end up having to reinstal everything from the ground up for i am unable to log in......I was woundering if someone could give me clear simple instructions as to how to update my server without haveing to completely reinstall everything thanks in advance for help with this issue.

Problem two. I'm new to all this (im sure youve noticed ) but i have a weird problem thats been making me angry since day one (2months back). anytime i attempt to not allow servers to register on my server it doesnt work i have to have the following values set the way youll see them

# If set to true any GameServer can register on your login's free slots
AcceptNewGameServer = True

# If false, the licence (after the login) will not be shown
ShowLicence = True

if I so much as set them both to false or to false and true ..when i go to start the game server it tell's me wrong hexid >.< how the hell do i fix this? also i want to know how im supposed to know which server im useing on my gameserver table in navicat ill show you what i see below

server id --- hexid ---- host ----
1 ---81d589df728e8e7781cf14da249486c (nothing under host)
2 ---81d589df728e8e7781cf14da249486c -71.176.34.135
3 ---81d589df728e8e7781cf14da249486c -71.176.34.135
(this continues 8 server id collums down)
my question for this is how do i know which is my server and which ones arnt so i can delete them off my list? or if i delete them all will that effect my game at all?

anyways i know i ask alot of questions im sure ill have more but thanks in advanced. Sorry if i broke any rules.
