Can not get photoshop to open or download from my plan.

​@CB Photographics Unfortunately you haven't given us no detailed infos about your issue and any information about your system. Therefore, all proposed solutions are a look into the crystal ball.

What do you mean with open or download? 

Do you have installed Photoshop? If yes, does this work inthe past and what has been changed on your system before the error occur?

Make sure the your system matches the system requirements. Adobe Photoshop on desktop technical requirements | Photoshop

Try a reset of the CC app. To reset the Creative Cloud desktop app, make sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R

If that fails, try to repair
