I have a mac. Yesterday I had an issue with an external hard drive which crashed on me. At the time ti crashed I had several files opened that were probably not fully saved to the external drive (or were in the process of saving). Since then, I can't open Acrobat. I click a file to open, or even the program from Applications and it won't open...I get the colored wheel. So, I have to force quit.
I tried running the unistaller to re-install the program...but the same thing happens. It won't open or do anything.
