hello friends, i need help! After two weeks of use ( i used 3 times after buying), my dongle stopped working. "No UFI DEVICE DETECTED" I tried to install on the other computer the same thing "no UFI..." (i tryed UFI_v1.2.0.419 and UFI_v1.2.0.454). My system is Windows 7 x64. What could happen and how to solve the problem?
