Amonetize - Fucked up Statistics and no invoice?

Alright so I have been there for like 3 months and currently have not received 1 invoice (I am just testing the network so do you have to earn over 50$ before it will show?)

Also the statistics always show's invalid reports of "How Much I Made"

Example:

See how much I made from a month to current date: $10
See how much I made from 3 months to current date: $3.50

Also lastly is there an advantage to having a silent install or no?

I have no problem with them
