Mysidia Adoptables Support Forum - Need Help Logging In

I just installed the script Version 1.2.4, but when I go to login,it says "Login Failed!
Sorry, we could not log you on with the details specified. You can try again or request a password reset." I know the password is right, and the password reset doesn't work. I Haven't edited any of the pages, either. Here is the code for my login.php:

PHP Code:


		
			
<?php



include("inc/functions.php");



//***************//

//  START SCRIPT //

//***************//



if($isloggedin == "yes"){



$article_title = $langislog;

$article_content = $langislogfull;



}

else{



//User is not logged in, so let's attempt to log them in...



$username = $_POST["username"];

$username = secure($username);

$password = $_POST["password"];

$password = secure($password);



//User is not logged in



$loginform = "<form name='form1' method='post' action='login.php'>

  <p>Username: 

    <input name='username' type='text' id='username'>

</form>";







if($loggedinname == "" and $password == ""){

// User is viewing login form

$article_title = "Member Login:";



$article_content = $loginform;

}

else if(($username != "" and $password == "") or ($username == "" and $password != "") ){



//Something was left blank

$article_content = "Something was left blank.  Please try logging in again.<br><br>{$loginform}";



}

// Try to log the user in

$password = passencr($username, $password);



$result = runquery("SELECT * FROM {$prefix}users WHERE username = '$username'") ;

$user = mysql_fetch_array($result);
