Raven Shield 1.56 fixed .exe?

[cyclops[0]]

I reinstalled Raven shield and updated from 1.0 to 1.56 and applied the fixed 1.56 .exe. When I go to start game it says I need to install the 2nd CD. When I did this before going from 1.0 to 1.55 and applied the fixed 1.55 I had no problem playing the game. Am I missing something here. Do I need to wait for the nocd.exe. I thought thats what the fixed .exe was?
