I currently have LW 5 but before I upgraded, I had LW 4 and experienced this problem. When I downloaded some files they had a certain size of mb. After a couple of times on LW, I noticed the size of the files showed 0 bytes..it read 0 bytes of 0 bytes (0%) completed. Does this mean the people who had these files are long gone and therefore, the sources are gone or does it mean there was some other error with the files?
