Even after fixing the URL for weather.com, DINAJ2 still says Loading.... I've restarted my computer, etc.
Same problem with me
I tried berryaaku's answer:

   Editing 
[mTemperature] and [mFeelsLike] RegExp values respectively to 

   
RegExp=<tmp>(-?\d+)</tmp>
   RegExp=<flik>(-?\d+)</flik>


This seemed to fix the loading issues for me.
Thanks, this fixed it for me, too!
