Bookmark import keeps getting cut off/errors

I am trying to import my Delicious bookmarks into Faves. Using the regular del.icio.us Importer page, I got about 700 of my most recent bookmarks imported without issue (out of several thousand), but when I try subsequent imports I can't get the importer to recognize any older bookmarks.

I also tried exporting my collection as a bookmarks file (1.7MB) via Delicious's website, then uploading it using Faves' regular bookmark importing tool, but I keep getting an "Oops!" error page.

Is there any additional way that I can get the rest of my bookmarks uploaded?
