I can't see any problem with your setup.
There is some difference between the board you and I have because I see the light on yours is green whereas mine is red but I don't know if that's the only difference or if there are more.
I would expect this to show up on an I2C scanner. Have you tried running the scanning program with any other I2C device to confirm it is working correctly?
The only other thing I can think of is to tie AD0 (the address pin) to ground, though I've never found this to be a requirement.
