PHP код:

    if(fexist(UserPath(playerid)))
    {
        INI_ParseFile(UserPath(playerid), "LoadUser_%s", .bExtra = true, .extra = playerid);
          ShowPlayerDialog(playerid, DIALOG_LOGIN, DIALOG_STYLE_PASSWORD,"Login","{09B086}Type your password below to login.","Login","Quit");
    }
    else
    {
         ShowPlayerDialog(playerid, DIALOG_REGISTER, DIALOG_STYLE_PASSWORD,"REGISTER","{09B086}asdffadsfadf.","Register","Quit");
    }
if(pInfo[playerid][pIsBan] == 1)
    {
        SendClientMessage(playerid,colorenter,"You are banned from the server!");
        return Kick(playerid);
    } 


Try loading your data first, then check if he should be kicked.
The other way around doesn't work that good (checking if he should be banned, then afterwards loading his data which holds that info).
