Hello, I have a MacBook from 2008 that has worked perfectly the past 3+ years. Today I tried opening a PowerPoint file in Microsoft Office 2008, but the file never loaded - the Powerpoint icon bounced up and down for a while, and then all was still. The computer froze for 1-2 minutes before finally the "Powerpoint" orangeish logo appeared, but my file never opened. The same was true for Word when I tried to open a doc file. What's worse is that my computer slowed down during and briefly after this. I had to wait several minutes after trying to open the files before I forced-quit either Word or Powerpoint. Does anyone have any idea what might be going on? I last used the software on September 1st or 2nd and they were working just fine. I decided I would uninstall everything and reinstall when I get home later. Does that sound like a good idea? What if after reinstalling it still doesnt work? I *really really* need these programs to work this week as I am giving a big presentation on Saturday and need to get information from Word and make a new Powerpoint!! THANKS FOR READING I REALLY APPRECIATE ANY INPUT!
