Plugin broken

Hi,
I’m not sure if you still support this plugin or not. A recent change to woocommerce or wordpress has broken it. My single product pages stopped working, I deactivated this plugin and it was fixed. When trying to reactivate I got
“Fatal error: Uncaught Error: Using $this when not in object context in /home/wcptcoma/public_html/realplace/wp-content/plugins/woo-already-bought/woo-already-bought.php:17 Stack trace: #0 /home/wcptcoma/public_html/realplace/wp-includes/class-wp-hook.php(286): Woo_Already_Bought::activation(”) #1 /home/wcptcoma/public_html/realplace/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #2 /home/wcptcoma/public_html/realplace/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/wcptcoma/public_html/realplace/wp-admin/plugins.php(174): do_action(‘activate_woo-al…’) #4 {main} thrown in /home/wcptcoma/public_html/realplace/wp-content/plugins/woo-already-bought/woo-already-bought.php on line 17″
