If you select
eaDocX | File | Load Document Profile,
..and browse to the install directory of eaDocX (usually c:program fileseadocx) then the built-in profiles are installed there.

I think the one you’re looking for is now called ‘Use Case Detail’, as it has a bit more than just Structured Scenarios.
In v3.0, best think is to delete the ‘Link’ column, as that has been replaced, and I haven’t yet updated these built-in Profiles.
