Not sure who you know, so I won't recommend people I know on there doing stuff, to answer the other client issue assuming you're using LOTM, go into your game folder and find your update.dat file. Open it in Wordpad and change it from:
patch.camelot-europe.com:1280/updates/english/labyrinth/mpatch.dat
patch.camelot-europe.com:1280/updates/english/labyrinth/mpatch.dat
to
patch.daoc.net:1280/updates/labyrinth/mpatch.dat
patch.daoc.net:1280/updates/labyrinth/mpatch.dat
I'd personally keep a copy of your whole EU folder if you have room just in case. Other than that should work fine.
Hope this helps.
