Crimson Skies/No CD: help for an amateur please :)

[Col_Spankworthy]

Hi,
I've played my Crimson Skies to death. (V1.02, UK)
So.... I've finally found 2 files I think may help me, but I'm not sure.
One is 'CS v1.01 No CD', which sounds like what I want, but the wrong version (?).
The other is 'CS V1.02 Fixed Executable', which is the right version I think, but...is a fixed executable what I need? Can someone tell me what a fixed executable is?
Complete newbie in need of hand holding.
Ta muchly in anticipation.
