The computer which holds CF is about 25 years old now and has just failed to boot all morning, so it looks like I will need to transfer CF to a more modern system.
This will include a full upgrade of the software so it can run on a modern system, then restore the results from week 5 and try booting the modern system and check to make sure it all worked.
It's just a matter of buying the new software, downloading it and restoring the week 5 backup. Shouldn't take more than a few days, but just in case it does we may have a slight delay on the next deadline.
