according to

You must be the current owner of a mutex semaphore in order to release it.

User Action:

Request ownership of the mutex semaphore; then retry the command. You may have to contact the supplier of the running application.

How do you request ownership of the mutex semaphore???
Here is an interesting article explaining them a little bit:
Are you writing code that is putting locks and release locks on resources?  If so your error probably originates there.  If not you probably have a corrupt install and should reinstall SQL Server.
Or i guess if you have another add on application running that could be causing the problem.  Try removing all add-ins and killing all non critical running applications and let me know if the problem persists.

I'm not writing any code. There are several applications that run on this server and some use MSDE and one that runs on SQL. I will try and uninstall the application using SQL and I'll see what happens.
