Unrecognized Licence

Hello

I have a problem I can't solve, even after all the manipulations that have been recommended by Adobe.

I have an Adobe account with the Creative cloud (with Photoshop) on my 1st computer. I would like to install it on a second at the same time. But I only get the following message:

I already pay this formula and it does not recognize my Photoshop license. I tried everything without any results:

- check my payment information (up-to-date)

- sign out of my account CC on the 1st computer

- reconnect on the 2nd computer

- uninstall/reinstall photoshop

- get updates of applications

- reset the hosts file

I don't know what else to don and I really need help... If you have solutions, thank you very much in advance!
