I keep getting a notification whenever i try to open photoshop that says "could not initialize Photoshop because the scratch disks are full." and i dont know how to fix it. I tried downloading it to my external hardrive which has more space but it still gave me this message.
You don't need a phone number. You need to take control of your computer and make a LOT of free space. Photoshop is just telling you that your disk doesn't have enough room to work - and it needs a lot of space (20-30GB is the bare minimum).
(Of course you can ring Adobe and they will tell you the same thing, eventually).
