If all else fails...Her are a Couple of thing I tried and seemed to work. 1) I closed all other programs, (like photoshop etc) Photoshop inparticular likes to scoop up memory. 2) I empty the trash 3) I delete all the temp files 4) I shut the computer down and restarted it it, then opened Poser. I'm not an expert, but these did seem to work for me. Good Luck!
