Query: Very, very poorly designed and extremely buggy

I bought this software because I was desperate to find a any Chinese learning software, so I bought this one an also the Rosetta Chinese learning software.Chinese now is the worst software I ever used, the user interface is very poorly designed and it crashes all the time.The software offer you meaningless translations and the speech recognition part is completely unusable recording less than one second of speech, you never have time to finish a word before it's done recording.My only advice is do not buy this software!, Only the package looks nice. You're much better off with a book and a tape
