All records have disappeared

Hello! There was something strange. The module stably worked already half a year. Yesterday I have cleared turn in MassMailer and from the module all records have left. Records are absent both in AdminPanel and on a site. But they remained in the Database. Thus all references to concrete records work. I have added point Listing View in the main menu, but it haven't worked. Writes, what there is no page modules/? r=listing/view / {modzzz_listing_view_uri}. Please, prompt that could deteriorate!
