Lightroom 6 - Sign in required

[#1]

Dear community,

Today as often clickedon the LR shortcut towork on my photo but instead of launching normaly, I had the "Adobe Phtoshop Lightroom 6 Sign In " pop up. Than it directly goes to the Phtoshop Lightroom 6 Trial window. I click on License this software, put my Serial Number (bought in 2017) click on "Next" but instead of going to the next step, it reload the "Adobe Phtoshop Lightroom 6 Sign In " pop up.

Did not try to uninstall the software as I am not sure it will help and not sure I won t loose my catalog.

Any clue, on what happened?

Thanks,

Chris

Uninstalling will not lose any of your files, but I am not sure it will help.

Thanks, is there a way for me to check with an Adobe Customer Service representant? I have the original mail of the purchase.

Was Lightroom 6 installed on the computer you are working with when you purchased it in 2017?

Thanks Denis, no it was on a different computer. My lightroom was working fine , I used it on Jan 2nd this year.
