hello I bought an XD-V70L Digital Wireless 12-Freq. Lav Mic System, I upgraded the firmware of the receiver with the XD-V75 and the monkey and everything is ok, when I tried to update the firmware transmitter disappeared from me and the transmitter does not turn on anymore. In Italy, the service told me that I must to buy again, someone in Europe is able to replace the new firmware again and if you can give me a contact address? thanks
