PDFCreator don't work

Good morning to all,
I installed PDFCreator and I used it for a long time. Now it has stopped working. He does not give me any error, the list of recent documents see the PDF but the file does not exist!
I tried to uninstall and then reinstall but it does not solve the problem.
What can I do?
Thank you.

 Didn't work for me.  I had Adobe Reader 9.  I ran a repair installation (run Adobe Reader, click "Help" then "Repair..."  After that, it did something different -- it started doing the print, but then didn't finish.  Then I installed Adobe Reader 10, and still no resolution.

Good morning,
I solved the problem.
AcroRd32.exe was ruined. With the repair install Adobe has gone all right.
Thank you.
