Hi everyone, I just purchased Vegas Pro 13 with the offer I received in an email from MAGIX. It was $200 for Vegas Pro 13 + Vegas Pro 14 upgrade. When I received the confirmation email, it also had some other programs that I didn't realize came with this offer. In the email, they all have serial numbers and "Optional Authentication Codes". When I made my account here, there were no programs listed under "My software", so I went ahead and and registered Vegas Pro 13 with the serial number and machine ID. I then received an email with another different authentication code. Is that normal or did I mess something up? I haven't registered the DVD Architect Pro 6 yet incase it does the same thing. Thank you for any answers.
