Probs with AOE Rise of the Rajas RELOADED

Hi guys,

Just downloaded AOE II HD, Rise of the Rajas RELOADED's torrent off Piratebay. However, the game isn't working. The issue is Steam. "Game failed to initialize Steam. You must have Steam running"

Am I missing out on something, is there something else that I need along with it? Do I need the original/base AOE II?

Any related information is apreciated.

EDIT: I'm only looking to play the campaign
