My widget won't show up [closed]

Question

I have built a widget class such as (using pear naming standards):

class CoreTheme_Adminpanel_Widgets_Download extends WP_Widget{

    function CoreTheme_Adminpanel_Widgets_Download(){
        parent::__construct( false, 'Aisis Download Button' );

        $aisi_widget_options = array( 'classname' => 'download', 'description' => __('This widget will allow you to display a download button.', 'downlaod') );

        $aisis_control_options = array( 'width' => 300, 'height' => 350, 'id_base' => 'download-widget' );  
    }

    function widget($args, $instance){
        extract( $args );

        $url = $instance['url'];
        $title = $instance['title'];
        $show_info = $instance['info'];

        echo $before_widget;
        ?>
        <a href="<?php if($url){echo $url;}?>" class="btn btn-success btn-xlarge"><?php if($title){echo $title;}?></a>
        <div class="well"><p><?php if($show_info){echo $show_info; }?></p></div>
        <?php
        echo $show_info;

        echo $after_widget;
    }

    function update($new_instance, $old_instance){
        $instance = $old_instance;

        $instance['url'] = strip_tags( $new_instance['url'] );
        $instance['title'] = strip_tags( $new_instance['title'] );
        $instance['info'] = $new_instance['info'];

        return $instance;
    }   

    function form(){
        $instance = wp_parse_args((array)$instance);    

        echo '<label>Download Url</label>';

        if(!isset($insance['url'])){
            echo '<input type="url" name="'.$this->get_field_name('url').'" />';
        }else{
            echo '<input type="url" name="'.$this->get_field_name('url').'" value="'.$instance['url'].'"/>';
        }

        echo '<label>Download Button Title</label>';

        if(!isset($insance['title'])){
            echo '<input type="text" name="'.$this->get_field_name('title').'" />';
        }else{
            echo '<input type="text" name="'.$this->get_field_name('title').'" value="'.$instance['title'].'"/>';
        }

        echo '<label>Information</label>';

        if(!isset($insance['info'])){
            echo '<textarea name="'.$this->get_field_name('info').'"></textarea>';
        }else{
            echo '<textarea name="'.$this->get_field_name('info').'">'.$instance['info'].'</textarea>';
        }       

    }
}

// Register the widget
function register_download() {
    register_widget( 'CoreTheme_Adminpanel_Widgets_Download' );
}

// Add said action
add_action( 'widgets_init', 'register_download' );

My question is, according too: register_widget() I did every thing correctly, so where's my widget?

Just a stab:

In your constructor, try calling the parent constructor at the top:

function CoreTheme_Adminpanel_Widgets_Download(){
    // This line:
    parent::__construct( false, 'Aisis Download Button' );
    $aisi_widget_options = array( 'classname' => 'download', 'description' => __('This widget will allow you to display a download button.', 'downlaod') );

    $aisis_control_options = array( 'width' => 300, 'height' => 350, 'id_base' => 'download-widget' );
    $this->WP_Widget( 'download-widget', __('Aisis Download Buton', 'download'), $aisi_widget_options, $aisis_control_options );        
}

As to why this would work - I did a quick test with a widget I had locally, and it seemed to disable it when I removed the parent call...that's about it!

The key here people:

make sure to load the file you are trying to use before stating it doesn't work.
