Serious help!!

The reason this is so serious to me is because this game took me agesss to download(2.59GB) its Gabriel Knight 2: The Beast Within , so today it finished, I extracted the 6 files but they just turn into ISO type files, for example there called "GK2_CD1.nrg" so what can I do to actually run the game? Plz plz plz help me, thanks.

You either need to burn the images to individual cds, or you can create a virtual cd drive and mount the images. Using the later option is basically like emulating a CD drive and the files run straight from your hard drive.

If you want to burn the images to CD's, then use something like Nero.
If you want to mount them on a virtual drive i'd recommend a program called Alcohol 120%

:D dude! thanks a lot.
