Error with Subsonic services

[ConversePunk]

Hello guys, I just installed Subsonic and I'm having some troubles with the Subsonic service.
I'm using Windows 10, and following the "Setting up media folders" tutorial.
It says that I have to enter my Windows User and Password. I put my user but I don't have a password so I don't fill it, and I press OK, I restart the service as the guide says and I got this error https://prnt.sc/j96dja
