HI i do not know if i can write this here but i need help. I recently installed the photoshop cs4 and i have a little problem, when i open a psd file will be just fine, but when i open, having a background image i see a sign saying: "could not be met because there enough memory (RAM). " What do i do to use the psds files and no more see that poster? I hope someone reply to me i would appreciate it. And hopefully understand what  i wrote.
