Come on!  You must have learnt one little thing! . 

And the free download is just a sample anyway.

I had BYKI for learning Norwegian and although it´s a good program if you want to memorise vocabulary and have a lot of time. But I prefer grammar+vocabulary approach.

I bought the full version for Turkish and Croatian. It helps with the "basics" and gives an understanding of how to pronounce certian things. Its a great start and when used in combination with other products, it can act as an enhancer. I have it and rosetta stone. both are great and when used in conjunction with TC learning classes it just all kinda goes hand in hand.
