PROBLEM
When opening a project, ArcView tries to apply a theme definition query to a shapefile that was deleted from the project.
A theme definition is a property of the theme's attribute table (FTab), not the theme itself. The theme may have been deleted but the attribute table still exists in the project.
Remove the attribute table and save the project.
