after read your mail :
is very easy, in site
www.sws-redbox.com you not have any KEY file .. you can get only the Update file, so is normal is not work
if you have read well the site, you have 2 boutons : one KEY ( but will give all time error ) and one UPD, if you take UPD file not use it like KEY file for your box, is not correct
for run any soft you need correct KEY file, for have it read your ID and send it to your reseler, he have your correct KEY file for your personal box
you not need make more, only this and all work ok
good look
