I'm on 10.6.8 and can't install photoshop CS3. I've uninstalled and when I try to install, I get: please insert CS4. Doesn't sound right to me. I called Adobe and they wanted $69 to fix the problem. They looked at my crash reports and said it was my mac. I was afraid to let them touch my mac so I didn't go for it. Can anyone read crash reports and help me out? I'm not sure which to include, mac or adobe.
