Other than that the different between my conf. files and yours are just that at every area that said "Host" or "Listenhost" I ended up adding 127.0.0.1.<WorldDatabase Hostname = "localhost" Username = "root" Password = "qazxswedcv" Name = "world" Port = "3306" Type = "1">
<CharacterDatabase Hostname = "localhost" Username = "root" Password = "qazxswedcv" Name = "world" Port = "3306" Type = "1">

Port = "3306"
Type = "1">
