Macbook Pro with new battery not charging

[iamamac]

Hi,
I bought a new battery for my macbook pro 2,4ghz santa rosa.
After only 20 cycles, coconut was showing me its at 90% of its capacity so I thought it's time for a calibration.
I let the battery drain, then plugged the macsafe and surprise.. not charging!
what can i do? if i press the button on the battery, none of the green leds are flashing or turning on as they should
please help me!
