I think i know, what it could be...
From the following video I noticed that the rig is made with an older Cinema version (R18.041) and uses some scripting (xpresso, C.O.F.F.E.E., python?). Note that with every release, SDK changes a bit. Specifically, pay attention to
dropped C.O.F.F.E.E. support from R19+. Things may break, got corrupt or are simply set in a way it conflicts with Corona. For starters, does the rig at least work as demonstrated with release you're using?
In that case, if you haven't yet, contact creators.
Get their people to talk to Corona people.Howgh!;)
