trying to edit floppy contents w plpcfgbt but...

[mmrr]

'unable to open plpbt'
'unable to open plpbt.bin'
when i try to open plpbt.bin

i'm trying to boot a linuxdistro, puppy,
installed to a usbstick, usb1.1.

i had it working before the setup
choices when booting from unedited
floppy, but i resized the partions on
the usb and plop won't boot anymore
nor i can recall how i had plop setup

i used a fresh d/l to rawwrite to floppy
just now, copied plpcfgbt [all] to floppy

opened in dos...no joy
