You guys are over my head but I don't know who to ask. I have downloaded from the internet powerpoint slides and my notes from my Biology teacher for this semester. I use a shortcut to open these files on my desktop. Now my computer says the shoetcut won't work and my notes and files are gone. I have downloaded a new viewer and that doesn't help. I tried to open my work from the powerpoint viewer program and they won't open. It is just this file. My others open. It worked the last time on March 15. I even restoed my computer to an earlier date. No luck. Any ideas? Need help before my finals. Thanks
