Photoshop can't load cloud documents and unable to save new documents as jpeg and other formats.

I just updated the photoshop. And when I opened it, it tells me it can't load cloud documents. So, I decided to create a new file. When I tried to save it, it didn't show the option or unable to let me save my work as jpeg, png... I just looked up and followed all the steps on the other support post. But it still not working. Untill now I still can't figure the way out.
