It takes too long to download

Hi, sorry don't know if this is the correct place to post about my problems.

I am using NIS 2011 (trying to download right now 2012 version but it takes forever as they are big files, it says it'll take over 3 hrs to download :( I don't have that long... I have to log off line soon)

Since a week I couldn't download any updates for the 2011 version... The files were always too big, every day over 127 MB and it does it very slow... Why is it? I don't understand what's wrong?

My NIS version is 18.6.0.29

Explorer 9 I think...

Can you please help? I've been trying to download updates until now since over 4 hrs, and yesterday as well... It's very slow and same with the new version 2012 which I am trying to download right now... Many thanks
