LBC data files (MCF) can get very big because LBC stores icon image data in them even at image sizes that it doesn't really need. There is an option to clean up and minimize the use of image data in the Tools -> Maintenance menu.
The MCP should be tiny, they essentially just tell LBC what MCF file(s) were open and have some general options.
So, all your tree data is in an MCF file, which should be automatically backed up by LBC when you make changes.
And then the MCP files hold very little of value. If you lost your MCP file you would just start LBC and tell it to open the MCF which has all your data in it.
LBC should be auto creating backups regularly of your MCF files, so it's distressing if it wasn't.

I apologize for the delay in getting to this. If you still have an old MCF file with your latest nodes but its not visible, can you confirm this -- and let me know what happens when LBC launches or when you try to File -> Open it.. Does LBC complain or just not show on the screen. I will add some code now to try to fix up things if LBC finds itself off screen, which I suspect may be the problem.
