Counter Strike Mani Admin Help

[LIGHTS.[KayLee]]

So I have Mani Admin on my server. I can't get the admin to work, because everytime I try to use admin it pops up, "You are not authorized to use admin."
This is how my client.txt is;

"clients.txt"
{
"version" "1"
// This key group lists all your client players
"players"
{
// This must be a unique client name
"Gnome Chompski.<3HerJustin"
{
// Client real name
"name" "Gnome Chompski.<3 Her Justin"
//steam ID for client
"steam" "STEAM_0:1:24429111"
// IP address for client
"ip" "192.168.2.8"
// These are personal access flags for a player
"groups"
{
"Admin" "Serveradmin"
"Immunity" "Serveradmin"
}
}
}
// This must be a unique client name
"Jay/ManWhore<3MyKayLee"
{
// Client real name
"name" "Jay/ManWhore<3MyKayLee"
//Steam ID for user
"steam" "STEAM_0:1:25485249"
// These are personal access flags for a player
"groups"
{
"Admin" "Serveradmin"
"Immunity" "Serveradmin"
}
}
}
"Purple"
{
//steam ID for client
"steam" "STEAM_0:0:26020178"
// These are personal access flags for a player
"groups"
{
"Admin" "Serveradmin"
"Immunity" "Serveradmin"
}
}
}
// These are global groups of flags that can be assigned to clients
"groups"
{
"Immunity"
{
"Serveradmin" "a b c d e f g h i j k l m n o p q r s t u v x y afk ping autojoin grav Immunity"
"Clanmember" "a b c k n p ping grav autojoin Immunity"
"Teamadmin" "b k n ping Immunity"
"No Kick Ban" "b k Immunity"
"NoFun" "d f g i j l t Immunity"
}
"Admin"
{
"Serveradmin" "A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e"
"Serveradmin" "f g i k l m o p q q2 q3 r s t v w x y z admin client grav pban spray"

"No Rcon Or Sound" "e f g i j k l m o q s t v w x y z admin spray grav pban"
"No Rcon Or Sound" "client"
}
}
}

EDIT: So what am I doing wrong?

[street wizard]

cry

[G4Vi]

[Neddy]

Mani admin has more bugs then features. Get rid of it. Get Sourcemod.
