I have used PSE in the past and just updated to PSE 13. I uninstalled the old version before installing the new one. I also uninstalled my printer/scanner and reinstalled it. I tried to scan a photo into my computer and the import button was not functional for me to select the source which would have been my printer / scanner.
Any ideas what I might try to make the IMPORT functional? I am using a Macbook Pro. I also have the lasted updates up to date on the computer, including the latest operating system, Yosemite. Thanks for your help.
