Slic3r Port Disconnect (Stopping mid-print)

I've been having trouble with my brand new solidoodle 2. Almost every print that I've printed lately has been ruined by the fact that my printer suddenly stops and loses connection with my computer. I click disconnect and reconnect and then I get the message, "the port does not exist." I have tried everything from plugging the printer straight into the wall to changing the baud rate to 25,000. I am using a computer that I built last summer and using windows 7. It's really frustrating me and discouraging me from printing anything remotely large because I'm tired of wasting plastic and time. I know that I may have a faulty usb cable or faulty drivers at this time, but I don't know how to fix the drivers.  The RH log screen says nothing when the printer disconnects. The printer just stops mid-print and when I try to control the printer manually it doesn't respond. The only way that I can get the printer to connect again is by clicking disconnect in RH and then unplug/replug in the usb cable to my computer and then hit connect in RH again. If I do not unplug/replug the usb cable and just hit disconnect/connect I get the message "The port does not exist." Its very frustrating stuff. It doesn't look as if any damage has been done to the motherboard and the packaging looked well done with no damage done to the box when I received it. Any help is greatly appreciated.
