This action is not avaiable at the moment.

Is ıt a bug ? I liked 3 or 4 fb pages succesfully but I see this message when I clicked my last ten fb like pages. Could anybody help me ?

hi Dear

because the credits for this ad be ended .....

this because more people click the ad in same time so the credits for this ad will be ended quickly ...

so when you click you will find this message .................

Try to click on the ads quickly to catch the credits

I clicked them quickly but fanslave page was working slowly last night. May be this is the reason of why I saw that message. Thank you for answer
