You all should have read all the pages in this thread. The software posted on page 2, http://www.trolling.pwp.blueyonder.co.uk/DAB3/DaB3.exe , works fine. I have just used it today. I’ve also had problems with my old “DaB3.exe” refusing to log on but it seems that the new one (v3.003) is working fine. It has a new checkbox labeled “Use Alt Server” that, if ticked, did the trick for me.
Hope it helps.
