Wrong ethernet module? 12 pins on ENC28J60

I bough this component too, I couldn't make it work!!! I tried several libraries but it didn't work, I tried to edit some .cpp and .h files, but no success.
I have a mega2560, the IDE I used was 1.0.5 and the last one 1.6.4.

Were you able to make it work???? How did you do??

thank you very much
