How the hell do I play it?

[shafter111]

First off, Sorry to ask such a stupid question (you guys are all pro). I had the .mdf file (supposedly the DVD image file) for Splinter Cell Pandora Tommorrow. I used Undisker to extract the files. Then I ran set-up and so the game is installed. When I tried running it, it asked for the disk to install. Obviously I dont have it, and I know I need to use a software like, Alcohol 120% to get around this problem. I saw a few cracks for this game on gamecopyworld.com. I obviously installed those, in the directory where the game is installed. Now what do I do to actually play? How do I use Alcohol 120%? How do I use the cracks (if I need them at all)?

Guys this is the first time I am doing this, so please help me out. I am a rookie. Any link to go through the steps will help me out a lot too.

Will really appretiate some help
