Every time I open Adobe Reader 8 or Acrobat Pro, it immediately quits. I have no idea why this is and I have tried reinstalling, but no luck. This has been doing this for months, and I have used preview instead, but I really need Acrobat, so now I'm asking. I am running a registered version of Design Premium CS3 on an Macbook Pro. Has anyone else had this problem? Any idea of what I should do? Thanks!
