Well i used level because didn't noticed you had 'Admin'. Also, you are misinterpreting the usage of enums and variables.

Let's start:

pawn Code:

enum pInfo
{
    Admin
}
new PlayerData[MAX_PLAYERS][pInfo]; // Remember that this variable MUST be below the enum!

To save:

pawn Code:

dini_IntSet(file, "Admin", PlayerData[playerid][Admin]);

To load:

pawn Code:

PlayerData[playerid][Admin] = dini_Int(file, "Admin");

Also remember to clear the variables on player connect:

pawn Code:

public OnPlayerConnect(playerid)
{
    PlayerData[playerid][Admin] = 0;
    return 1;
}
