Help : SafeDisc 2.30.31 iso image wont work

[DarkStar]

Hi, im a newbie. I downloaded Emperor: Battle for dune as 4 iso images. I burned 1st disc with Nero, CD-Mate and Alcohol %120. I check the cd with Aray, it says SafeDisc 2.30.31. I setup (also restarted) DT (restart again). And set all emulations ON. I mount the images with DT, When the setup runs, there is a dialog "Title is: "Cannot locate the CD-ROM" and the message is "Please insert the correct CD-ROM, select OK then restart application"

Am i doing wrong or what is wrong?
