I just tried it and it seems to be working correctly, Try again and if the problem persists I shall investigate further or re-archive and re-upload the files.
CRC errors typically point to a corrupted download rather than a problem with the archive itself.
However, I'm going to update my archiving software, re-archive and upload the files as HF1.5 which fixes some very minor bugs to see if that fixes your problem.
Check back in the next half hour or so and it should be up.
