Renumbering starting with no number

NEED HELP RENUMBERING

Hi, I am trying to figure out a way to renumber files, in such a way that the new filenames start with the first file without any number and then the rest of the files being numbered sequentially starting from 1.

Expalanation: In Media Browser, (In Windows Media Center, Windows 7), backdrops must be named "backdrop, backdrop1, backdrop2, backdrop3...and so on. The first file needs to be without a number and then the rest sequentially starting from 1. Unfortunately, the closest I can come with BRU is to use the option to start with 0, then go back and rename the first file removing the 0.

Assuming that you still want ALL files(except-1st) numbered as FolderName#
Your commandline would be:
brc32 /nofolders /removename /appendfolder:p::1 /autonumber:0:1:s:-:10:1 /regexp:(.*)(-0)$:\1 /regexp:(.*)-(\d+)$:\1\2 /execute

Its easy to 'shell-integrate' this if you need it often (as a folder's right-click option)
But it gives NO filtering/warning, so one mis-click could be deadly
I usually put things like this in a batch (only to display the directory & give a final warning)
