I'm running Vista and I have an Administrator account but the other user doesn't. I've shared the folder so the other user can have full permissions on it. We're both saving to the same folder but never at the same time. Currently I'm getting this message when I launch Limewire 4.16 on my administrator account: "Your save folder is not valid. It may have been deleted, you may not have permissions to write to it, or there may be another problem. Please choose a different folder." Whatever folder I choose now, I get this message. The other user is not getting this message right now.
