Messiah 2 installation instructions?

[Sage]

I found the messiah webpage and downloaded the instuctions in pdf format. There must be something wrong with my acrobat reader because it says error in color cr6. I don't know what that means but all of the diagrams come up solid black. Is there a place to get another version of adobe acrobat reader? I'm using win 98 SE.

Thanks for any advice!!
