I created a database in Base using only provided functionality (i.e., using HSQL). All worked fine for several months, including yesterday, but today the database won’t open. When I tried to open it either through Finder or through the LibreOffice menu, I get a filter selection box. I don’t know what to do. I have not updated either the OS or LibreOffice recently.
OS X 10.6.8
LibreOffice 4.0.2.2
Thanks,
