i am still trying to resolve why my appointments+ plug

Hi i am still trying to resolve why my appointments+ plug in is not working. In previous requests for help I was assigned a support person but have not heard anything however Ashok suggested I check if the wp_app_workers table was there and it is not . I know nothing about the tech side can someone please have a look and see what can be done or advise nice and simply please. The initial problem was that the appointments + plug in would not attache a service provider to the service. I really needthis sorted its been quite a few days now. Thanks.
