Yes, I think this is the case. It happened to another user too. Don't
worry, it's easy to recover :-)

You could download your developer key again by submitting the serial
number and UUID of your laptop here:


If you no longer have this information, one way to retrieve it from the
XO is creating  a Collection Stick as explained here:


The file LAPTOPS.DAT on the USB stick is really a text file containing
data for one laptop per line. I can't remember the exact record format,
but the serial number and UUID should be easy to recognize.
