ahrimans

I stopped playing Ahrimans prophecy ages ago ( for no particular reason ) and now I dont remember what to do. At all. please help! How do you fight/ cast magic/ check quests or journal/ get to inventory/ open a map/ see what you have to do next or see your progress? Anything would be good, thanks

I have downloaded the file in zip , so now how do i apply it to the game? I have the "god" goodie and the gold goodie. Any help?
