Have received the above and saved it onto my computer where it is sitting saying that the file is a Microsoft Power Point Slide Show with size 1,240kb. When I go to open it with MS Power Point Viewer I get a blank white screen. When I click the mouse it goes to a blank black screen with "End of slide show, click to exit" at the top. Is there a fault with what has been sent to me or am I doing something wrong? I have received and viewed other .pps files and viewed them without any dramas.
