License problems with Photoshop CC

I Signed Adobe Cluod and down load and install Lightromm & Photoshop. Photoshop stops without an error messagel. I tried to logout and login, following the adobe solution,  but allways asked me once to activate the license. I recivied a message with the confirmation that I can work with photoshop but ask me again for the same and still Photoshop continues in the samen statusclose without error message. Please can you hel me.

Thanks in advance.
