WP Property help

I just installed wp property on wordpress 3.04 and don’t see add property and when I click all properties I get the below error

Warning: require_once(/home/content/01/8676901/html/wp-admin/includes/class-wp-list-table.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/01/8676901/html/wp-content/plugins/wp-property/core/class_list_table.php on line 2

Fatal error: require_once() [function.require]: Failed opening required ‘/home/content/01/8676901/html/wp-admin/includes/class-wp-list-table.php’ (include_path=’.:/usr/local/php5/lib/php’) in /home/content/01/8676901/html/wp-content/plugins/wp-property/core/class_list_table.php on line 2

My guess is something isn’t getting installed and the settings are being retained. How do I delete the entire plug in???? I removed the two default types Building and floorplan and I imagine it messed something up.
