All of my print configurations are now gone after installation of v1R5.1 x64.

How can I prevent this from happening in the future? It is as though they were overwritten by the process of installing the latest version.

I attempted to recreate new print configuration for the sheet size I had previously used which was ANSI C for a virtual printer that created PDF files. The printable area is no longer the same and portions of the title block and page borders are unprintable. How can I modify the print area for a given printer? I had no difficulty using this virtual printer previously.

Is there a way to lock the paper size to a sheet tab without using the print configuration? This data seems to be something that should stay with the drawing file and not get overwritten by a new version of DraftSight.
