I am running a Mini-Mac with OS 10.4.7. I have had PD for 6 mos. and have been trying to install it. No version number on any of the packaging or manuals or disk. I assume it is 3.0. The install seems to go well, message "successfully completed" or equivalent. I get the little orange box in the applications folder and a separate PD folder. When I click on the icon I get the Install window. I have uninstalled and repeated the install. Same thing. Stated another way, once installed I am unable start the program, only able to start the install process again. Should I wait for the full moon to try again?
