I can not send calculator Apps for the emulator

[Davidro]

I can't send anything to the Calculator Emulator. Does not appear in the Send button calculator. In the emulator, it appears that key send as soon as I connect with the calculator and can send data to it. There is command of testicles EU can do to make sure a machine is working well, for example, the USB driver?
Made, including updates, firmware:
version of the application: 20140702v6031
operating system version: V 0.032.6030
version of the program: 201472 (6031)
the most: I received the calculator yesterday, day 1. and I doesn't seem to work well. There is a channel for warranty support you can contact?
Grateful
Davi
