Help with THC Hydra

[Altor]

I've got a problem with THC Hydra. Whenever I put in the command for cracking a web form, being:

hydra -l <username> -P BG_wordlist_and_digits_1-1_all_combinations.txt <domain name> http-post-form "/user/login:xuser=^USER^&xpass=^PASS^&do.auth.x=Login:LOGIN FAILED!" -V

Instead of starting the command, Hydra just resets and I get the following text again:

Hydra is a tool to guess/crack valid login/password pairs.
Licensed under AGPL v3.0. The newest version is always available at;
https://github.com/vanhauser-thc/thc-hydra
Please don't use in military or secret service organizations, or for illegal
purposes. (This is a wish and non-binding - most such people do not care about
laws and ethics anyway - and tell themselves they are one of the good ones.)

Example:  hydra -l user -P passlist.txt ftp://192.168.0.1

How can I make Hydra execute the command?
