Cannot access virus signature database server

Discontinued Products Comodo Rescue Disk - CRD
1

Hello,
I have been using Comodo Rescue Disk for two years without problems.
In the last days (I have tried on 18/02/2015 and 21/02/2015), when I start the scan and the update procedure starts, I get the following error: “cannot access virus signature database server”.
On 18/02/2015 it seemed it started downloading the bases, but stopped after a while.
Any ideas?

If I manually download and manually import the bases from the following URL, should they work?

Thanks.

I am having the same issue. I can confirm that the computer is connected to a network and can ping google.com and comodo.com from XTerm.

Please advise. Thank you!
