I have this error crop up in the backend when I try to visit the shop, this is the error >>

An error has Occurred
1146 Table 'brookstonej34.z8jh6_virtuemart_userfield_plg_realex_hpp_api' doesn't exist SQL=SELECT * FROM `z8jh6_virtuemart_userfield_plg_realex_hpp_api` WHERE `virtuemart_user_id` = "515" ORDER BY `modified_on` DESC

Im not sure how to fix it and how its come about, I thought it might be to do with Realex Hpp Api payment plugin but I unpublished it and its still appearing.

Thanks
