[92eatos]

I spent over a 5 hours to find where is mistake for this vote system...
It do every thing fine but when i press to spend vote points it says there is no realm, you dont have character and there is no rewards...But everything is setted right it worked before i instaled windows 7 and php 5.3.0
So can any one try to update this script

<?php

class Rewards
{
	function Title()
	{
		?>
        	Reward panel
<?php
	}

	function GetRealmData()
	{

		$Con = mysql_connect(MYSQL_HOST,MYSQL_USER,MYSQL_PASS,true);
		mysql_select_db(MYSQL_DB,$Con);
		
		$RealmInfo = "{";
		//get each realm
		$res = mysql_query("SELECT id,name,sqlhost,sqluser,sqlpass,chardb FROM realms",$Con);
		echo mysql_error();
		while($Row = mysql_fetch_array($res))
		{
			$RealmInfo .= $Row['id'].":{name:\"".$Row['name']."\"},";
		}
		if(strlen($RealmInfo) > 1)
			$RealmInfo = substr($RealmInfo,0,strlen($RealmInfo)-1)."}";
		else
			$RealmInfo .='}';
		mysql_close($Con);
		return $RealmInfo;
	}
	
	function GetCharData()
	{
		//get data that will be used to select the character.
		$Con = mysql_connect(MYSQL_HOST,MYSQL_USER,MYSQL_PASS,true);
		mysql_select_db(MYSQL_DB,$Con);
