NOLF GOTY copying?

[bruceg]

Hi,

I copied NOLF Game of the Year Edition, however, when I install, it says at the end of installation "file NOLF.REZ doesn't match the file in the setup's .cab file. Medium may be corrupt"

Because of that error, does that mean the copy I made is bad?? The game surprisingly seems to work (at least tested the first level), but am wondering if it may get screwed up later in the game because of that installation error message...

Thanks if anyone knows...

Bruce
