Hi,
Sorry, yes, I meant Activity Monitor. When you see the beach ball, switch over to Activity Monitor and select the 'Photoshop' process. The Sample Processes button should become active.
Before trying the webpage download, can you try quitting the Creative Cloud application and then restarting? (Creative Cloud desktop application FAQ)
If that doesn't get the previous 14.s version to show up, then you can try downloading the installer from here: Download New Adobe CC Trials: Direct Links (no Assistant/Manager) | ProDesignTools
regards,
steve
