Very New

[puttssee]

Hey everyone. I am very new to this. I downloaded a game called Medieval Total War. It was an iso file. had no idea what an iso file was. Looked on the internet to find something that would open an iso file. Came accross this site. Downloaded the software. Mounted the first file installed it then when asked for second file mounted it and it installed. Now when I go to play it shows me a message insert original disc. I don't have original disk. How do Iopen this thanks
