Purchased BD bundle from OWC with Toast 12 Titanium and Roxio HD/BD Plug in on physical DVD. No problem installing Toast 12. Registered both software programs and received email acknowledging the registrations but no support codes were given with either email acknowledgement. The Roxio HD/BD plug in will not install on my Mac Pro (2013 model) using OS 10.9.5. The HD/BD installer has a line to accept the HD/BD plug in serial number but when I enter the registered serial number, the "Next" button remains grayed out so installation of the HD/BD plug in does not take place. Since the software was delivered in a physical disk, Digital River can not help me. Roxio has not sent me a support code for either of my registered software products (Toast 12 Titanium or the HD/BD Plug-in) so I am rather orphaned in this tech support loop where I can't get into Roxio and get this problem resolved. Any help would be appreciated.
