If upgrading to Pro, it's best to delete the LW preferences folder as Remoc suggested. There's also the Gnutella file that for some versions of LW was out of date & needs replacing.

Sometimes a combination of these ideas works http://www.gnutellaforums.com/connec...t-connect.html as it has for me even recently. Sometimes too many incomplete files can crowd out LW from connecting properly. There may be other reasons, but at a guess UPnP is not communicating properly between LW & your modem/router because too many signals being sent out at the time LW is trying to connect, be it due to incomplete files, OOB, Ultrapeer settings, etc.

If still no good; System details - help us to help you (click on blue link) would give us some clues.

BTW Pro support is very slow dare I say it.

BTW do you know what 'fake' files are? Can you recognise them? They tend to crowd the connection & best deleted if recognised.
