After dev Installation on localhost, immediately I opened the component (from admin) I found these errors, could someone please tell me what to do?

Joomla 1.5
com_muscol_2.2.1_community_pro

Notice: Undefined variable: artists in E:\\wamp\\www\\hustler81\\administrator\\components\\com_muscol\\muscol.php on line 107

Notice: Undefined variable: songs in E:\\wamp\\www\\hustler81\\administrator\\components\\com_muscol\\muscol.php on line 108

Also when viewing the component via link from the Menu I get the following:

artist->artist_name; ?>
: artist->num_albums; ?>
artist->num_songs){ $link_songs = JRoute::_( 'index.php?option=com_muscol&view=songs&id='. $this->artist->id . $itemid); $songs = "".JText::_('Songs').""; } else $songs = JText::_('Songs'); ?> : artist->num_songs; ?>
artist->albums as $album){ $link_album = JRoute::_( 'index.php?option=com_muscol&view=album&id='. $album->id . $itemid); $image_album = MusColHelper::createThumbnail($album->image, $album->name, $this->params->get('thumb_size_artists_1'), array("title" => $album->name)); ?>

I have followed all the installation instructions found here: www.joomlamusicsolutions.com/en/support/installation.html except i dont seem to have the System plugin - Joomla 1.5. I have the component up and running on my live site and couldn't find it installed either but it works fine. I guess I didnt download it so this could be the source of the issue on the localhost but it looks like it may have came out after my subscription expired as it shows an added date of 5/14/2012 and my subscription ended on 5/5/2012 lol. I searched and found that I have everything else but that, weird. I have the Error reporting off in both PHP and Joomla Global settings but still get these errors. Any insight would be greatly appreciated as I try to make some changes to template to upload to live site.
