I paid for CC, but Lightroom won't install. Trial version is useless - an empty screen. I have no serial # - I'm guessing because nothing installed

Question

How do I get rid of the trial version and get the one I paid for?

I don't have enough information from your post, and I am not sure if you are on mac or pc,  but see if one of these fits your issue:
If you don't see "install" by Lightroom in the application manager, please first try signing out and back in:

If creative cloud is asking for a serial number when you start a Creative Cloud (CC) application, see this link: Creative Cloud applications ask for serial number
IF when you open an application that's part your Creative Cloud membership and you see a message stating you're running a trial, see this link:
Creative Cloud applications unexpectedly revert to trial mode | CS6, CCM
If you updated the desktop installer and the screen is blank: try this:
Rename the opm.db file.
Close the Creative Cloud application if it's running.
Navigate to the OOBE folder.
Windows: [System drive]:\Users\[username]\AppData\Local\Adobe\OOBE
Mac OS: /User/<username>/Library/Application Support/Adobe/OOBE folder
Rename the opm.db file to opm_old.db
Launch Creative Cloud
