I paid for CC and have been using PS. However, I can't get to LR. It says I need a serial Number. I contacted Adobe and they said that is not the case. Then I got cut off. Any fix?
If you paid for CC-full-suite or CC-Photography-Plan then you should have a CC-licensed version of LR available, but only if you uninstall the serial-number-licensed LR you apparently have, now. At least try that, uninstall LR 5, log out of the CC app using Gear / Preferences / Account / Sign-Out, reboot, log back into the CC app, and see if LR is one of the items listed.
