The problem is that “Self Hosted Plugins” is a service, not an actual plugin. I’ve given you a “license” to it, but since it’s not a plugin, I’m not sure how we validate against it. Previously, builds checked against a setting in developer.coronalabs.com, not marketplace.coronalabs.com.
I’ll speak with Engineering. If this isn’t working, we may have to make a fake plugin.
But regardless, since I need to know what email address you’re authenticating against in the Corona simulator and making sure you’re using the same email address in Marketplace, lets take this to support@coronalabs.com so that we are not exposing your email address here in the forums.
