Yeah same here with the 1062 error. Similar mentions on this as above. Main thing was I couldn't view cb-profile. I disabled cb activity and things worked ok, turned it back on and disabled gj and things worked fine. So I have left gj disabled. 2.7 to rc1 install. Appreciate that it's beta, just letting you guys know.
