Silo is broken

Tried to do the user enumeration with odat and it just didnt work even though i was doing everything correctly and odat installed successfully. I had to read the walkthrough and i put the valid entry on a file, and it still wouldnt work. I know it is a retired machine but i am paying 20 dollars for the subscription and this shouldnt be such a waste of time. am i the only one that experienced difficulties during the username bruteforce attempt? I tried nmap with my custom files and still didnt work. They would refuse to use the password combo because they knew the account was locked.
