What would the best way to download it... Portable Offline Browser or Metaproduct Inquiry.
I found these websites:
Select the Project that partially downloaded the site and then click the Browse With AutoSave button on the Home tab of the Ribbon. Offline Explorer Pro should download missing files.
... FRIV We're really sorry. There has been a loading error. Please check that you entered the domain www.friv.com correctly into your browser...
but if I open http://www.friv.com/ in any browser its open correctly without any problem.
Whats going wrong.
Some may work this way, some - not.
