I've been digging through the registry and comparing what MM's provisioning cabs setup for Arcsoft. I've found a few settings that I've moved over, like UAProf is now pointing to the VZW xml and the UserAgent string is set correctly for VZW. Still can't get it to send, but receiving still appears to work. Still haven't tried the latest Leo update, other than trying to run it so it could tell me I didn't have a Leo.
