Wrong Table names

Hello,
It’s me again…
I found another problem:
The plugin tries to access a table called wp_ewd_uwpm_email_send_events but it has created a table called ewd_uwpm_email_send_events because when it initializes the table name in Main.php for the first time it tries to add $wpdb->prefix but didn’t initialize the global variable $wpdb first.

I also added a feature to make abandoned cart email dependent on specific products in cart.
I’d like to share my changes with you. Do you want to create a GitHub repository or do you prefer a ZIP file with my updates?
