I purchased and installed the plugin as directed

I purchased and installed the plugin as directed in the instructions on both domains. Everything is turned on and ready to go but the sites did not sync. I even created a new test user thinking it will sync prospectively and not retrospectively but even that one did not show up on the subsite. I am running Magic Members plugin on the master site and Extended Users plugin on the subsite. Could that be the reason why they don't sync, because they here is a mismatch of information entered during registration that can not be transfered to the subsite? Or does the plugin sync every x minutes/hours because its been 24 hours and still not synced. Thanks!
