I posted about Babylon dictionary 7 giveaway event (maybe it's babylon dictionary 8 giveaway) before. It's a really useful software for someone to learn languages. But it's not cheap for somebody to afford. If using illegal licenses isn't not your choice (of cause, I don't like it,too), I'm sure you will
happy to find a free alternative ^^. Even information of this software has been posted on many forums and sites, but for my site visitors' benefit, who may not know about its exist, I post an article about this software on my blog. Not sure about its legal right of its dictionaries, hope its owner deliberated on this issue before giving those dictionaries to its users !
