I opened my database today and can see my menus and the data in the tables and forms by clicking through the menus, but when I click in the database window on the tables tab, I it's all blank and I get "Operation invalid without a current index. (Error 3019)". Also if I click on either the query/forms/macros tabs, I get "<Index name> isn't an index in this table. Look in the Indexes collection of the TableDef object to determine the valid index names. (Error 3015)". I do have a backup, and can use that, but what happened and can it be fixed?
