MySQL Error - WebMatrix 3

I tried to set up a WordPress site in WebMatrix 3. I created a username and password and WebMatrix was installing the components. Somehow it got hung up, so I closed the program.

I reopened and tried again. When I got to Type of Database, it showed this:

MySQL (Installed)

Administrator username: root

Password: ************* (prefilled in)

So I hit continue and got an error saying:

"The specified password for user account 'root' is not valid, or failed to connect to the database server.

I tried to retype my password to no avail.

What can I do to get past this point?

Thanks
