Photoshop Elements 2019 keeps asking to login and enter the serial

Hi everyone,

This week I bought a digital copy of Adobe Premiere Elements 2019 and Adobe Photoshop Elements 2019. I want to use Adobe Premiere Elements 2019 on my PC, and Adobe Photoshop Elements 2019 on a laptop.

First I installed Adobe Premiere Elements on my PC. This installation went perfectly fine. However, Photoshop Elements 2019 keeps asking me to login and enter my serialkey. I followed the steps below:

1. I went to https://redeem.licenses.adobe.com/getserial/  signed in and entered the code that I got when I bought the software online;
2. The Adobe website gave me my Photoshop Elements 2019 serial number. I saved this number safely in my password manager;
3. I clicked the download button to download the software;
4. I started the installer, it asked me to login (which I did), and completed the installation without any issues;
5. I rebooted the laptop (to be sure) and started Adobe Photoshop Elements 2019 and clicked the Photo Editor.
6. It asked me to login (which I did), and clicked the License this software button. I entered the serial number that the Adobe Redeem page gave me after I entered the redeem/voucher code;
7. After this, the screen disappears and prompt me to login again (step 6).

I did the following to try to solve this issue:

• Completely remove Adobe Photoshop Elements 2019, run a file/registry cleaning tool (CCleaner), did a reboot and installed the software again;
• Went to Adobe Account and logged in. I entered the serial number there and It registered Adobe Photoshop Elements 2019, so the serial number is valid.
• Made sure I entered the correct Adobe ID and password;

The above options didn't solve my issue. Does anyone have a suggestion what I can do?

Thanks in advance!
