I have Adobe Reader on my Vista OS. When I try to open a PDF file, I either get a message that states I must exit Adobe and when I click "OK," the file opens. However, on occasion, I'll get the following error message in which I cannot open the file and a blank Adobe window opens:

"file is damaged or cannot be repaired."

Next time you can successfully open the file, Save As a new file name. If there is any corruption, saving it as a new file may fix the problem.
