Hello,I think that you have to change the voltage from 3.3 V to 5 Volt. If you look at the break-out board of ADAFRUIT http://www.adafruit.com/products/269 than you can you see that they converted the voltage!Kind regards
I would make sure that you have a good solder joint in the SOIC to DIP. use a straight pin contact to the top of the pins of the SOIC and the regular lead to the DIP. so that you are seeing if the continuity is there. I found an open this way that was pretty elusive.
