So I just downloaded Battle For Middle Earth 2...
 

I downloaded it from www.thepiratebay.org, the 5.44gb one. And I'm having trouble figuring out how to unzip it all. If someone has downloaded this also... could you tell me exactly what you unzipped, and the order...? I got the installation files out... but it doenst detect the first disc, it came with a crack... but where do I put it? I think i need someone to walkme though this. Thank you.

First, what file type is/are the file(s) you downloaded for the game? What have you done in attempts to get the game installed and working?
If it's an ISO, mount it with something like Daemon tools and run the installer. (If it's a BIN/CUE, mount or burn the CUE file.) Directions for the crack should come inside an NFO file with the game. If not, they're in there somewhere. NFO files can be opened in Notepad or something more "robust," like DAMN NFO viewer.
