Continuous error message when trying to open/download adobe files

[billydbillyd]

I can't open/download adobe files from e-mails or websites.  Never had problems until about a month or two ago and now it never works.  I keep getting the message "There was an error opening this document.  This file is already open or in use by another application."  How do I fix this?  Thank you.
