It is basicly not adviced to load g-codes from external drive, but to copy the file to a local disk and load it that way.
When you load the file from the external USB drive does the blue LED blinks (goes off for some time)?
If so then the issue is probably that your computer is too "weak" or a drivers issue of the USB flash drive.
You can try to use a different USB flahs drive and you can try to reinstall the USB drivers for the flash drive and you can try a different, more powerful computer.
