I have set up the free trial and appear logged in,but can't get any futher?

Can you say more about what happens when you log in? Are you at the screen in the game where you see a spinning station overlaid with the character selection and password screen? If so, you may need to manually set your antivirus or security software to allow Vendetta. If you have a router, you may need to permit your router to allow Vendetta.

sounds like you have only logged into the website? If you havent downloaded it then click here: http://www.vendetta-online.com/x/download

Once its downloaded you run it and log in there, then its kind of impossible to miss it. When you run it, it will not run straight away there will be an update section and when it has completed there the button 'Play Vendetta' Will become active.

[EDIT] Guess its not relevant not, just noticed how old this post is
