Cura cannot connect to lulzbot mini

Ok I got a Mini last week and everything was going fine when i left work friday. Now I come back and cura cannot see the printer. I get the following in cura.

“Changing monitoring state from ‘Offline’ to ‘Opening serial port’
Connecting to: COM7 with baudrate: 115200 (configured)
Unexpected error while connecting to serial port: COM7 SerialException: ‘could not open port COM7: [Error 2] The system cannot find the file specified.’ @
Found no ports to try for auto detection
Changing monitoring state from ‘Opening serial port’ to ‘Error: Failed to autodetect serial port.’”

I have looked in device manager and I see a “3D Printer powered by RAMBo (COM7)” under ports.

Windows 8.1 pro X64
Cura - 15.02.1-1.03

Hmm. it seems that i would not work with either usb on the left of my laptop despite working all last week,
Problem kinda fixed.

I’m not quite sure what went wrong. If it happens again can you take a screenshot? Would also be helpful to know if this error occurred while a print was going on or if you just had Cura open and not using it. Also appreciate your follow up post!
