It looks like perhaps your network is configured incorrectly.  When you paste 
the address 4.standard-reconcile.dfhuynh.user.dev.freebaseapps.com in your 
browser's address bar, does it bring up a page titled "Reconciliation Service 
API Test Dashboard"?

Does your network have a proxy or firewall which needs to be configured to 
allow Refine to access the external network?

Thanks for your support!

As regards the first question I tried to open the mentioned service and is 
possible to do it both in Explorer and in Chrome.

I also checked the proxy settings and actually I'm using a proxy server for my 
LAN..what do you mean with configuring the proxy to allow Refine to access 
external network?

I have some news...I changed the proxy settings and now at least Freebase works 
fine but I have some problems with the RDF extension yet trying to use DBpedia 
so I have opened an issue in the proper place asking for a solution to the 
problem.

Thanks
