You should still receive the registration confirmation e-mail even with the error. At least that's what happened to me. Also, if you log in your Roxio MyAccount, you should see Toast 10 listed in Your Registered Products.
gaper1 replied to Davids8477's question in Toast 9
how BDMV folder was made? What's the manufacturer and model number of your Blu-ray player? Are you able to play BD movie with sound on that Blu-ray player?
do you have anything listed as subscribed right now? It's likely that you did not configure your setting properly since you are the only one with issue on forum notification.
As a last resort, you can change your e-mail address for the forum account to a different one.
