Why can't I play my Album slideshow?

Question

I recently upgraded to iPhoto '11 v9.5 on my new MacBook Pro laptop. Following the upgrade I can no longer play my complete slideshows that I created in "Albums"? Instead the initial photo is loaded and is then repeatedly loaded - the remainder of the photo's, which are clearly visible and in the correct sequence, are ignored? I didn't have this problem prior to the upgrade! How can I make all the photo's play when I select the "Slideshow" button? Very frustrating! Appreciate any help. Thanks.

Try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion, Mt. Lion or Mavericks delete the contents the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder.
3 - reboot, launch iPhoto, reset its preferences and try again.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.
If you're running Mavericks, 10.9,  go to your Home folder and use the View ➙ Show View Options menu to bring the this window:
where you can check the Show Library Folder checkbox.
