I have a question about install complete with RevenYou

Today , I started PPI with RevenYou . My campaign just had a video on youtube . Then I got some download some hour ago . I didn't know why someone completed install but i didn't have comission ?

So how i can get more traffic or install ? Please give me some advise to grow up my campaign

Just means the person installed your software but declined the toolbars/adware. They will only pay you if users install their addon software.
