Hmm, thats wierd sometimes your Firewall or Antivirus blocks it out. It happened to me before check your flash and browser settings along as well.
Nice earnings per click, actually. How much traffic and adsense earnings do you get daily? I agree with the idea of moving the ad block up. It's better to the position where people see the ads without having to scroll the window down.
Well I got 54500 views in 1 month so probably so Im making 1500 views per day. Also I will move it a bit up but dont want to make my site just ads. Also I have only started so I made $2.70 cents so far.
heck yeah .81 cents for 3 click is very good, that is like 27 cents per click, I wish all clicks were atleast that much.
