ananisikim,you miss something,like probably many free users in last 3 days.
After entering captcha you see this:
[SLIDE]http://www10.pic-upload.de/01.03.13/2g9e8ru414hj.jpg[/SLIDE]
"Download with rapidgators download manager" is checked by default.
So free user must uncheck this to download your file.
If not, will start download this .exe file only.
I have avira antivirus and avira scream adware/virus alert.
So thats why downloads number are less last days.
