Have been away from the prepwork and now lost progress? Help

I was away from the prepwork for a month or more working on other things and now I am back to it to finish up (was probably about halfway through it). But it doesn’t show any of the tasks as being completed anymore. I really don’t want to waste hours redoing all of the prep work. It still shows my points as being a little over 9000 but that doesn’t help me. Is there any way I can get my progress back, or can I at least just skip everything I know I already did?

Never mind i was just on version 2 when before I was working on version 1. Why are there two versions now?
