We haven't done much work recently on Rei due to other (soon-to-be-
launched) projects running here at 3Di. So it's possible that some
incompatibilities have arisen with changes to upstream OpenSim. If you
could post here on the mailing list some specific error messages along
with details of your environment, we might be able to help. For now
the mailing list is better than the IRC channel if you want to discuss
Rei.
Thanks,
