I'm also having trouble with the mod install file - this is before I get to the mod-enabler!!! (by the way, the link above is broken).
The installer is asking where to extract to. Is this a temp directory or the DW disk location? Only if it's the disk location then my link is steam://rungameid/1600 - it seems not to have a c:\program files\dangerous waters folder or whatever it would be called.
The one line of 'instructions' clearly isn't enough
