Ardour and Jack not working
Im completly new to ardour and ubuntu (have only been using it since thursday)
ardour and jack started off working fine, no problems at all, but today they stopped working:
jack would not start and showed the message :
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 the messages window shows:

If i try to just open ardour it says:
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.
any ideas what the problem is? id be very grateful for help.
P.s. if it is useful i am using a USB behringer sound card
thanks a lot
