Addmefast facebook like not working

Hi guys, I have a problem with the addmefast likes on fanpage. I just registered to the website, and I went to Facebook Likes and I see the like buttons, once I click on it, the likes are increasing, it stays 1-2 seconds, and it gets back to the original likes, and I don't get any points.

What do you think ? Is this some bug or just my browser ?

Happend this to some of you guys too ?

Thanks in advance, any comment is appreciated.
