I have a machine with 8 GB RAM, about 40GB of free space on my system/program drive (a SSD unit), and have Photoshop CS 6 set up to page on drive C (although I have 4 rotating drives available with lots of free space).
I tried to load a small Photoshop file and got an error message that I was low on memory -- it would not let me process that file. So I rebooted. That didn't help. Next I went to Preferences menu and changed the memory from 50% to 75%. BIG MISTAKE: now I can't even load Photoshop.
Short of reinstalling, is there any way I can recover from this?
