i can never connect to www.limewire.com -- it's as if there is no such server so far as my browser is conerned. what's going on there?

also (i'll post this q elsewhere soon properly, and after having looked at limewire.com first if pos) "could not move to library" in lw 4.2.6 in os x. i've been using that version for some time and never seen "could not move to library" before. now within the space of about three days i see it twice. after it has occured downloads.dat a downloads.bak are gone, rendering all my partial downloads useless: hours of dowloading time wasted -- something lw's good at doing. does anyone know what's going on with that?

thanks
