Years ago i tried downloading the Adobe trial version, but i couldn't download any of the apps, because even if they downloaded, an error would appear and it would cancel automatically, so i gave up trying and was never able to use any of the apps.
Recently I noticed I needed Adobe After Effects and Lightroom, so i tried downloading it again (i have a different laptop from back then) Now Creative Cload keeps loading infinitely and doesn't stop, because of this i can't download anything, and i haven't been able to use the trial (i made a new account to be able to use the trial).
Have you actually installed Creative Cloud Desktop? If not you can get it from the link below. Then launch CC Desktop, sign-in and go to the Apps tab. You should then be able to start a 7 day trial for any app not already tried.
If CC desktop is not launching, try uninstalling and then download again.
