Did you use a data/sync cable?
What happens when you double tap(single tap might work) the reset on the Leonardo? Does the L-LED fade in/out for approx 8 seconds? And at the same time Windows device manager will / should show something like Arduino Leonardo Bootloader?
Which version of the IDE are you using?
I have no idea what code 45 is but it might be cause by a bug in your sketch.
Would you be referring to this error code as described by DiskInternals:
Several peripheral devices are always connected to the computer, such as a mouse, keyboard, and other USB-connected devices. When the OS is unable to communicate with the connected device, you see error code 45. This means that Windows does not recognize the connected peripheral.
