Every time I try, it claims that the source file is corrupted - this has happened with two clean installs of FO2, as well as two Restoration installers. Anyone know how to fix? Restoration v.2.3.3.

EDIT: It also scrambles the colours of FO2.

EDIT2: I've fixed the scrambling by going into ddraw.ini and switching dx9 on.

EDIT3: I've got it as good as I can get it by installing the resolution mod and unofficial patch first and then the Restoration mod.

Unofficial patch is already included in Restoration Project. Don't be surprised with bugs, since you have installed the mod incorrectly.

try re-downloading the Restoration mod.
