Title: Really Disappointing
Review: I purchased this book over the summer and just tried to use it this week... unfortunately, I can't open any of the files that you need to do the lessons. Every time I try, I get an "unexpected file format" error, and I have tried on a couple of different computers. Of course, since I purchased it so long ago, I can't even return it. I am upset that the publishers didn't make an effort to make sure the files would work for everyone. There is nothing anywhere in the book that specifies if you need to be using Mac or Windows, and I can't even complain to the publishers because their Web site is all in Korean. $30 wasted.
Is the review positive or negative?
