I've recently download the Trial versions of CS5 and Elements 9. When I installed CS5 last week it worked fine, no issues. This week it started crashing everytime I tried to 'Save As' and later 'Save'. I googled the issue and found no hits. I uninstalled CS5 and have now installed Elements 9. It crashed almost immediately when I tried to open a JPG file. Is this a known issue and I've just missed finding anything? Is it a Mac issue or should I hit up the Adobe forums?
