Keynote Quits When Opening Files

Question

Keynote 09 is doing some bizarre things - most seem to have started when KN disappeared from my computer and I reinstalled it. I have read through the various threads where opening files causes KN to crash, and the workarounds did not seem to clear up the problem.
I was able to open the files that crash on another Mac running KN09 with no problem, saved the file with a different name, and then could open it in my MBP with no problem. However, I then was unable to open another presentation that now causes the same behavior. So out of the 4 presentations I have done recently, 2 have failed to open, with one cured after opening/saving in another Mac.
I hate to think I have to go through this process each time a file decides it won't open, and there seems to be no way to tell when it will happen. A very unreliable situation that obviously can't be left alone, as I have courses to teach and if I can't rely on the files to open I might as well not bother with KN.
I am also amazed at the various suggestions that cause people to jump through hoops in the hopes of getting programs to work. It's not like these are 3rd party programs - if Apple can't get their own software to work on Apple's - well, that doesn't bode well for the rest f us who use these things, now does it?

Answer 1

For what it's worth, my experience of Keynote crashing has been when the file I'm opening contains a video file, and usually a large size QT at that. It only seemed to happen if I opened the file by double clicking on it's icon. If I had Keynote open, and hit +O, or opened the file by navigating File>Open, it was fine.
Hope this helps Dan.
