This is a game-changer. It suggests that there is a problem with your MiKTeX installation (assuming MiKTeX is what you're using, which on Windows is quite likely). Am I right that View > PDF (pdflatex) is also no longer available? After the reconfiguration, does LyX still offer View > DVI and Export > DVI? If DVI still works but pdflatex is gone, try running the MiKTeX settings application (should be in your Start menu, I think under MiKTeX > Maintenance). Run "Update Formats" and "Refresh FNDB" on the general tab, then reconfigure LyX again and see if that helps. Paul
