If you've paid off your Splice rent-to-own subscription and open your XLN Audio plug-in you will see the following message:
Clicking on the link in the message will take you to your product key that you can register to your account at www.xlnaudio.com. If you've already registered your product but still see this message when opening your plug-in the reason is probably one of the following:
1. You have yet to run the XLN Online Installer to authorize your paid off plug-in.
or
2. You have run the XLN Online Installer but you're logged in with a different account than the one you registered your product to. Since the XLN Online Installer picks up your Splice licenses while you're renting the plug-in it's possible that you're seeing the plug-in in the listing of the installer with a Splice logo next to it, this is however not the paid off plug-in that you just registered. If this might be the case click on your name or the person icon in the top right corner of the installer and log out. Then log back in with the account you registered your plug-in to.
If you have plug-ins that you use in both accounts you can get in touch with XLN Audio Support to have the accounts merged so that you can get all your plug-ins authorized.
If you've run the XLN Online Installer and made sure that you're logged in with the account that you registered the plug-in to but the plug-in remains unauthorized, please contact XLN Audio Support.
