All SmartSound plugin activation codes are assigned to your specific serial number. If your purchased plugin code is not accepted, you most likely are using a different serial number than the one that the code was assigned to. You can enter your correct serial number by clicking the Help menu and choosing "Change Serial Number". Enter the serial number that was provided with the plugin activation code, then enter the activation code again and it should unlock the plugin features.
If you purchased a plugin activation code for the free Express Track version of Sonicfire Pro and then later upgrade to the full Scoring Edition, your plugin activation code will need to be reassigned. Please email support(at)smartsound.com with your new serial number and the order number from your plugin purchase and a new code will be promptly assigned to you.
If you purchased the Avid/Pinnacle Studio Plugin from Avid or Pinnacle, they will have assigned you a free Express Track serial number along with the corresponding activation code. If you already own the Scoring Edition of Sonicfire Pro, we will need to assign you a new code. Please forward your purchase confirmation to support(at)smartsound.com and we will verify your purchase and reassign your activation code.
