I have subscribed to Adobe Creative Cloud for a while now. At present I am unable to access it from the logo on my Mac. Also I am unable to download programmes. When I go to My Account it says the packages I have downloaded are not registered and asks for serial numbers. This has happened before but I can't remember how to fix...
Is the CC apps like Photoshop , Illustrator ...etc asking for serial number when you try to launch ?
There are no serial numbers associated with Adobe CC.
In case you still get the pop up for serial number, please refer to the help document below:
You may also try to check your host file for any Adobe blocked entries.
In case there are any blocked Adobe entries, please delete them and then save the file.
