Adobe Reader encountered a problem error

Hi, I encountered an error message while opening a PDF file using Adobe Reader 9.1.
See the error message below.

Adobe Reader has encountered a problem and needs to close. We are sorry for the inconvenience.
I tried uninstalling and installing the Adobe Reader software but still the same thing happened.
I might have to go back in using Adobe Reader 8, but I want a newer version.
Please help!
