(sorry for my bad english, but i'm italian ^^.)

To play Nightfall is necessary to first install Ultima Online Mondain Legacy (which you can download from here `)CLICK HERE FOR DOWNLOAD
(the question: do you want a shortcut on the desktop UO, answer no.)

I recommend, you should not make autopatch UO!

Installed Ultima you have to download our MULS: CLICK HERE FOR DOWNLOAD.
You have to uncompress the RAR to the Ultima Online folder (They should be here: C: \ Program Files \ EA Games \ Ultima Online Mondain's Legacy \) and tell him to replace all files .

At this point in the last folder you will find a file called: client.exe
And with a double click you can open NIGHTFALL! (You'll see a black screen for three seconds and then will send `to the login screen.)

And to create an account? Simple: autoaccount is enabled, ie means that if you invent a new account name and a new password, you will create an account automatically.
