comp game says please insert disc when started

i made a copy of a game called diablo 2 and the expansion for a friend. it installs fine i used alcohol 120% to burn the image.
but when i go to play it, it says please insert cd into drive. but its already there did i burn it wrong or something cus a few other games worked fine when i burnt them.

 

You burned it fine its the games copy protection.

 

Scan the play disc with a-ray scanner. Burn with alcohol using the profile a-ray came up with. --- SecuROM ----
