What did the SFV file say (provided if there was one)?
The "<font color=yellow>Unexpected end of archive</font>" error just means that one or more of the archives are corrupt. Corrupt could mean the file wasn't fully downloaded, thus file size mismatch. Corrupt could also mean file size is correct but at least one byte has been changed within the archive. Both cases of corrupt leads to a different CRC. The SFV file contains the correct CRC for each file, thus it serves as a way to validate the files you've downloaded.
