Please help! Impossible to import my Blogger files

to wordpress. I’ve tried several “fixes” including setting up a .wordpress account, exporting my blogger files to a .blogspot account and trying to export B to A. Still, it hangs after about 80 posts and I get a “set users” message. I also tried the Google Wxr export tool, but my file is too large at 25.5mb. I am trying to move a longstanding blog with about 5800 posts, and am near the point of giving up the ghost on this one. Can anyone help?
