I am running tiger 10.4.7 and have photoshop elements 3.0 installed. I want to reformat my HD and reinstall this program but I lost the install disc. How can I make/burn a new disc that will actually install? I tried using the Backup 3.0 program from .mac. I also tried to use Toast titanium 7 with no luck. It says, it cannot open the program because of missing or incorrect personal data. It never shows the install window to enter serial number etc.. So I am assuming the install part of the program does not back up? I am not even sure it exists on my HD from the install disc. Any help would be greatly appreciated.
