I have a problem with Halo CE

I have the full version of Halo CE (not sure if there is a demo/trial) and when I entered my CD Key and installed it then tried to run it, it came up with "Please insert the correct Halo CD-ROM, select OK and restart application". And that's where my problem comes in, I DOWNLOADED the Halo CE so I DO NOT have the CD. Is there a way to play it without the CD?

If so then post it and I will Thank/Rep+ you. (I know a lot of people say they will and don't but I don't lie).

Uh yea....Use a no cd crack..

My little brother plays it, you can try and use the game patch+crack .exe and see if it'll work but I'm not sure. It wont let me upload it on MPGH but here is the virus scan. So if you want it I'll upload it and pm you the link.
