Not enough memory (RAM)? Can't change Performance as well!
Hi all,
Recently, the Photoshop can't save my work. It says that the RAM-Memory is full. Despite I didn't face this problem on the past. I'm sure there is enough RAM space and I don't open other programs while using Photoshop.
See the error message below:

I've tried to change the performance and I got another message:

Any suggestions?
