mb.miniaudioplayer Throws error on "Insert the Code" click

Hi,

I think this plugin is great but today I found a problem.

The media files are appearing as links. I attempted to turn them back into a player by following the same procedure described in the video. When I click “Insert the code” I receive the following message:

Notice: Undefined index: plugin_version in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 3 Notice: Undefined index: includes_url in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 4 Notice: Undefined index: plugins_url in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 5 Notice: Undefined index: charset in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 6 Notice: Undefined index: exclude_class in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 7 Notice: Undefined index: donate in C:\domains\MyAuthorWebsiteWP\wp-content\plugins\wp-miniaudioplayer\maptinymce\maplayertinymce.php on line 14

The lines in maplayertinymce.php are
$plugin_version = $_GET['plugin_version'];
$includes_url = $_GET['includes_url'];
$plugins_url = $_GET['plugins_url'];
$charset = $_GET['charset'];
$exclude_class = $_GET['exclude_class'];
…
$donate = $_GET['donate'];

I don’t think that anything in my WP Network has changed since last Friday.

I’m using WP 3.5 with a Multi-site install.

The webpage in question is: http://www.myauthorwebsite.net/tim-forbes/gallery/

All 6 of the mp3 files were working beautifully on Friday morning. Maybe the problem isn’t with the player files but I would appreciate any advice.

Thank you!
