If you downloaded attacklab before 2/11/2016 1:40pm, then I am very sorry to say, but you will have to re-download the lab from autolab and start over.
If you have already started the lab (meaning you have a scoreboard entry as of 1:40pm) we will give you an extra grace day if you need it. Please just contact email@example.com.
Very sorry for the inconvience.
Thanks and good luck!
