Creative Cloud chat support (all Creative Cloud customer service issues)
Thanks for your response, John,
I'm not sure what browsers and firewall have to do with this issue. I have been using Creative Cloud as a desktop app since first subscribing to the Adobe Creative Cloud, and downloaded all of the apps that I use on a daily basis way back then. The only change between seeing all of my apps and not seeing any of them was updating the actual Creative Cloud app itself. There were no other changes. Here is a screen shot of what I saw when attempting to update Acrobat. Below that are two screen shots that may be a signal that my Creative Cloud app is corrupt. Please let me know how to proceed.
