Old Customized Reference Types Lost

I had numberous customized reference types (e.g., “Edited and Translated Book”), with corresponding customized footnote and bibliography templates. I just noticed that all of those customized reference types have dissapeared (perhaps when I upgraded to X7.1). Is there any way to get them back? Please help!

Thank you, 


If you backed-up the modifications by exporting them as an xml file you could import the file to recreate the reference types - but without that file you may need to recreate those custom reference tempates.
