I downloaded Ardour yesterday, it worked, edited an audio file done. Come back today it wont start I get this:

Ardour could not start JACK 

There are several possible reasons:

1) You requested audio parameters that are not supported..
2) JACK is running as another user.

Please consider the possibilities, and perhaps try different parameters.

So I try and look at qjackctl to see what happening there. When I try to start JACK I get

D-BUS: JACK server could not be started.

then

Could not connect to JACK server as client.
- Overall operation failed.
- Unable to connect to server.
Please check the messages window for more info.

and this is the message box in JACK.
