Click on revmob redirected

After i finished my game in unity, i installed revmob package, and setup my ads . The ads display correctly, my problem is that when you click on and add it first wants to open up something in a browser then redirects to market. that is a problem because first it asks you with which browser do you want to open that dummy link, point at which you can skip the ad by clicking back . Looking at other apps with revmob this doesn't seem to happen, ads go directly to market . What could be wrong ?
