Thaks for your help. But something is not working. What do I do as soon as download the attachment

I think I misunderstood your question. By 'the attatchment' I assume you mean the hostslists.txt file(s) you are finding here? If you forgot where you saved it to, go to start -> find -> files or computers: and look for hostslist.txt on all hard drives. Open the xolox folder, and drag the downloaded hostslist.txt file from the find window into it, it shoudl ask if you want to over-write, say yes.
