You would be better off using the sme command line.
Save this command to a file and you can reuse it whenever you want to download the next iso that is available. By using rsync you will save a lot of download as the download will be compared with your original file and only what is different will need to be downloaded.
It won't help much the first time i fyou don;t already have an old iso, as you will have to download the whole iso, but it may help if you only get partially completed, as you won't need to download the bit you already have again. You could use the faulty iso file you already have as that will probably save a lot of download time.
pico smeiso
(type the following all on one line and save, make sure the space & dot are included at the end. ctrl o to save ctrl x to exit)
rsync --recursive --verbose --archive --partial --progress rsync://ftp.ibiblio.org/pub/linux/distributions/smeserver/releases/7/iso/smeserver.iso .
copy your old iso file (with the name of smeserver.iso) to a clean folder on sme, and copy the script above to that folder
then do
. smeiso
from that folder.
It will download the new iso from ibiblio
Run
md5sum smeserver.iso
afterwards to check the md5sum & it must match exactly the md5sum shown at ibiblio
