LBC makes extensive backups automatically as well - it is very very highly likely that your configuration file is just sitting in that directory. (I mean i really went overboard making sure the program keeps good backups automatically and also is very careful about saving good versions before overwriting older versions).
SO, first step: copy or zip up your entire LaunchBar Commander directory, just in case.
When you get this message:
"There are no LaunchBars/Docks or Tray Menus currently visible in the configuration file" It doesnt meant your configuration file is gone, just that it's not actually "loaded"
(because LBC lets you have multiple launchbar files open at the same time - this is a confusing issue and i may try to improve this a bit so it's less scary!).
So just go to preferences, and go to the menu File -> Open File.
Now if you remember what you named your configuration file, just open it.
If you don't, just try sorting by date.
You will be loading a .mcf file. The DEFAULT name of the default launchbar is MyLaunchBar.mcf, so that will be the name if you didn't reload it.
You might see a bunch of backup files as well - that's why i suggest you might sort by date.
Let us know how it works out for you!
