Serum asks for serial number after Re-activating rent to own plan

Hey! I took a break from the rent to own plan for serum a while but i went a head and started it again. the payment went through and i updated serum via the splice client. but inside my DAW (FL Studio 12) serum then wanted my serial number, which i obviously don't have. I re-installed serum a couple of times and even changed the install location but it still wants my serial number. Any advice or should i talk to splice instead? Thank you/Max

Thanks for writing in. 
When using Splice RTO, you should  not  be asked for a product key for Serum.  

If you are, this means one of a few possibilities:

• you had previously installed an old copy Serum on the computer and it is (now) running 
• Splice has not deposited a license on your computer (e.g. update Splice and log in) <- very likely if "new computer"
• Splice has revoked a license from a failed payment (?) <-  very likely if it worked prior…

Keep in mind you need to be connected to Splice online at least once every 3 days.  Once you have paid off Serum this is no longer needed.

(windows) You can go to  C:\%localappdata%\Splice and verify you see a Serum.lic file
 
Also, here's boilerplate message from Splice (and me I guess now!):

Please make sure you have deleted any previous versions of Serum you have on your computer. Then confirm that you are signed into the Splice app (the Splice logo will appear in your menubar) and have the latest version of the Splice client installed. The current version for OSX is 2.1, and for Windows it's 1.2.15. If you need to download the Splice app, you can do so here: splice.com/download

If you need to re-install Serum, open the client and navigate to the 'Plugins' Tab and click 'Reinstall'

You can also download the Serum installer here: https://splice.com/plugins/install/serum
