You'll have to rezero your overlay file and start over then... You can do it
manually from a windows or linux box but the dd command is a little
different for each. On a linux box it's something like:

dd if=/dev/zero of=/mount/path/LiveOS/overlay-{LABEL}-{UUID} bs=1M
count={size of overlay in MB}

Or on windows (the dd.exe is located under tools in the liveusb-creator
directory)

dd.exe if=/dev/zero of={drive letter}:\LiveOS\overlay-{LABEL}-{UUID} bs=1M
count={size of overlay in MB}

Just look at the current name of your overlay file and overwrite it rather
than looking up the LABEL and UUID.

I, like others, have created an extra entry in my syslinx.cfg without the
overlay option just in case I hose my overlay file and still want to be able
to use it.
