First of all, it really is unsafe to be downloading files from strangers.
Second, we dont help with mass filesharing because it isnt safe, and most of the files being shared are illegal, and its against the AUP of many networks and providers
Giving the unlikely benefit of the doubt that this is happening to you when you are trying to get a legal file from a friend:
in any mIRC window type /help dcc server
use the search feature here set to all forums, and all dates, try using alternate server as search term
you may be blocking whatever port they are using in firewall/router.
the person running the fserv could be having probs, which is very common, so ask your friend
