My HD has 9.41 GB of 15.9 GB free. Last defrag was about a month ago. I added all of the file sizes up (according to the resumeinfo.txt) and came up with 618.9 MB. This is more that the 591 MB that I had said in the earlier post (I think it was just the way windows reported the size) but I checked each segment and found that it was very close to what I had calculated. My thought was that if one of the segments was corrupt then i could possibly drop the one segment instead to the whole job. After this I was ****ed so I decided to see if cancel download worked. It did. I think it is more of problem with Xolox trying to connect to the other computer (eg. the increasing queue), but I saw nothing suspicious looking in resumeinfo.txt. I guess I'll just try it again. Thanks.
