i have just connected to my VPN service with US and UK ip addresses and tested few files larger than 1GB
as a result my stats showed 0.026 per download and 0.026x1000 = 26$ not 35$

now i can assume it's the same thing with other file sizes and this explains drops in earnings since yesterday.
you say the coder fix some bugs but seems like there are some new occured. and btw i have not accused you for cheating and scamming. YET.
