So I'm trying to import an URL list into HTTrack with the following data:

<http://students.washington.edu/achen89/missingfiles.txt> 

The problem is that HTTrack seems to skip over some files for some reason
(although it downloads the vast majority of them to disk). Is there a way to
ensure that every link gets downloaded? The URLs are very similar, and I
turned off URL Hacks. 

Thanks!
