[Solved] Can't start Webadmin - Address already in use

[VaiN]

I renamed the file and allowed it to generate, it's the same as it was:

; This file controls the webadmin feature of MCServer
; Username format: [User:*username*]
; Password format: Password=*password*; for example:
; [User:admin]
; Password=admin

I had already set up the login. It just didn't mention any port option by default.
