In Photo Gallery Live, I am unable to open photos that are stored on my external hard drive.  I have not had this issue in the past.  Even after including folders from the hard drive using FILE-> Include Folder->Add, I am unable to access the folders or any newer photos that are stored on the external hard drive.  I've closed and reopened Photo Gallery Live, and the folders I've added aren't even listed when I open "FILE->Include Folder" again.  Any help is appreciated!
