# Importing a latex file with bibliography into Lyx

When I import a Latex file that contains an explicit bibliography (\begin{thebibliography}.. \end{thebibliography}etc. from a .bbl file) I get an error message: Unrecognized parameter [Name where Name is the first \bibitem in the bibliography.


What is puzzling is that I used to do this without any trouble, but now it fails with any file I try.
Any ideas?
