Update failed - now LMS won't start

When trying to update to 7.9.3 (was 7.9.1), which failed, LMS stopped. Now, won't start even as Administrator. I opened Control Panel as Administrator, clicked on "Start Logitech Media Server" - it initially says its running, but after a couple of seconds it stops. Tried several times, no luck. Suggestions?

Update: simply went ahead and installed 8.0 and now the server starts. Unfortunately, I now have to re-set many preferences, but at least it works.
