When I try to open Acrobat XI Pro I receive an error message (Error 16) advising me to uninstall and reinstall the software.  I am concerned that if I uninstall the software that I will have to purchase it again and I do not have the original key which I would have received when I purchased the software. Does anyone have any suggestions for me?
