If you're already using the "hax 2.7" payloads for HomeBrew and the latest release HBL CIA Payloads (which you should if you had it working on 10.7) then all you should have to do is rename it.
I think I had never updated the payload in ages. It was still on 9.2 for some reason. I went to Smealum's HBL page, generated a 10.7 payload, and renamed that. Now it works fine.
