I can't send aplets from PC to HP 39gs

[Mairon Oliveira de Lima]

I've been having some trouble to send aplets that I downloaded from the Internet to my HP 39gs. Both Conn3x and HPx9G+ driver have already been installed and seem to be working fine (the images attached here were taken directly from the calculator using the screen capture option). I tried to install Snake (https://www.hpcalc.org/details/5100) while following the tutorial on "Mastering the hp 39gs & hp 40gs->Receiving from PC to calculator", but, instead of seeing a list of available aplets, the only thing listed is "Other...". Even when I click "Other...", If I try to get the file by its name I receive a message saying that the file could not be found.
Please notice that the other way around (aplet from calculator to PC) seems to be working perfectly. My OS is Windows 8.1 x64.
Any help is very appreciated. Thanks!
