USB booting :: Install to USB Pendrive not working



When I choose the Install to USB Pendrive option Under DSL CDROM version 0.9.3 or 0.9.3 it wont work.  Very quickly a box appears for a fraction of a second probably with an error which I can't see cause it happens so fast and then the box closes.  Do you need to do this under root access or something?   Is it a priviledge/permission problem?  If root access is required how does one do it that way?  Thanks :)
the script wants to download something called frugal_usb.tar.gz. just be connected when you run "install to USB pendrive"
I thought I was but I'll double check that and thanks.
I'm also having problems with getting DSL to boot completely.  It hangs at "searching for usb."  Any ideas?
It downloaded the image or frugal but it bombed on the install.  I wonder if this is a permission thing.  Immediately after bombing I opened root-access and ran mdsl-load frugal_usb.tar.gz then echo "mtools etc.. THEN frugal_usb.sh and then the install to pen/usb drive worked.
