Problem - Audacity is already running

I was wondering if anyone else has received this warning before and what they did to solve it. I am unable to open audacity or any file projects I have and have already tried force quitting the software and uninstalling/reinstalling the software. Whenever I attempt to open the application I get this warning:

"The system has detected that another copy of Audacity is running.
Running two copies of Audacity simultaneously may cause
data loss or cause your system to crash.

Use the New or Open commands in the currently running Audacity
process to open multiple projects simultaneously."

Please let me know.
