After many happy weeks of downloading, suddenly LW leaves all successfully downloaded files in my shared file as blank paper icons, not mp3s, and won't play them from LW, or from the Shared file itself, which gives the message "could not find the application program that created document named ___" and suggests only Entourage, uselessly. I'd thought it was a memory problem but recently upgraded my RAM and files I discarded as useless were still big and MP3 sized. Why won't Limewire reward all this waiting around with useful files all of a sudden? I'm on a Mac Powerbook G3 series, using itunes from versiontracker, so far happily.
