Mobo Genie is not identifying any of my phone on Windows 7

MoboGenie does not seems to be working well on my system and I am not able to figure out why. I am having around 4 to 5 android phones at my home. All are using it. I am using MoboGenie as the only option to backup my data. It works with my Samsung phone, but a number of time it gives me a issue. I am not able to figure out why it is not detecting the device. I am using a single cable here. The good thing of using this software is that it automatically syncs everything. When I connect it starts the backup. But from last few days it is not working. It keeps on giving me error and I am not able to find any resolution to fix this thing. Can anyone help.
