Clearing cookies.

I clear my cookies about twice a week on Google chrome. I did it earlier today and since i did that whenever i've clicked on watch video to earn tokens tab on top eleven a message comes up saying NO MORE VIDEOS. It has done that more frequently since clearing my cookies and have not had as many videos come up.
Does anyone else on top eleven on google chrome clear their cookies regularly and if so has it affected how many videos they are able to watch by and earn tokens?

Since I wrote this I have earned 4 tokens by watching videos, so i don't think it was to do with clearing my cookies, I think it would have happened anyway, whether I'd have cleared my cookies or not. Clearing my cookies in the past hasn't affected how many videos I can watch. I don't spend any money on tokens on top eleven, and I'm not going to start either, I earn just over 400 tokens a season by watching videos and filling in surveys.
