Here's some suggestions to get you started.

Click on the blue failed button.   Take note of the contents which pop up.   Search for information using that and the qe-def error.   

I'm assuming you have installed and configured the necessary sql server stuff for compatible mode. 

Here's some links.  There's also the install and configuration guide.

The good news is that your dqm connection works.  Is there any particular reason why you need both compatible and DQM?
