I need help with an i3 pro W starting problem

[Challa]

Hello! I'm Melania, from Italy.

I've just bought and assembled a Prusa I3 pro W, but I'm an absolute newbie in the 3D printing world and I need your help (please)

The printer is assembled, LCD working, leds flashing, but it doesn't move. I connected it to the pc and it detected the printer, but it looks like the pc and the printer speaks two different languages https://trackeasy.fun/usps/ https://showbox.tools/ .
I uploaded the proW firmware with Arduino on the printer, but nothing moves...
Maybe I need proW drivers for the pc, but if it's that, I can't find them anywhere ç___ç

What can I do???
