I am not getting points again for downloads?

I am not getting points again for downloads? Some days I get points some days I dont? What is wrong with the tracking?

sometimes they work, sometimes they dont. you just gotta keep trying. i do some of the join just register valid info and join. they are quite good and tend to pay out alot. my advise is give that a go or the questionares.

Mine is exactly the same sometimes they work, and mostly they don't.
