AE Edit Template

Hi Guys, basically i purchased a template on videohive ([login to view URL]) for a slideshow which he wants playing on his wedding day. I have the images placed in correctly however they seem to rotate very quickly and i want to increase the time of each image to around 10 seconds rather then 1 second. I also want to remove 3 place holder sliders which have a heart shape. I seem to have worked out how to remove the heart shape but not the place holder. I would appreciate any help in it or if you are able to tweak the template for me i would really love that. The template only opens properly in cs4, u can open it in cs5 and cs6 but it does not convert the project properly. if u dont have cs4 i have a portable copy. It is less then a 5 min job for someone who knows cs Thanks in advance!
