Vast numbers of errors including duplicate keys. 

Yes, it sounds like the database is already there. Drop it first
(assuming you don't need it), then recreate it so it's empty.

I have no idea where the database is located on your system - and a
database isn't just a file you can save anyway. You can use pg_dump to
export it to a data file, the same way as you did with your original
database.

None of the databases are "in" pgAdmin. pgAdmin is just a client tool
that connects to the database server, in the same way as pg_dump, psql
or your application will. Somewhere on your machine is a "data
directory", on Windows this is C:\Program Files\PostgreSQL\9.X\data by
default; this contains the actual databases, but they're just a bunch
of data files that you can't do anything with directly (and don't be
tempted to delete anything from the pg_xlog or pg_clog directories -
that will break the system).

The Help Contents in pgAdmin should open a local file. There also
should be some Help options on the Start Menu under PostgreSQL for the
database server, which will be the same as the online docs.

Please note that I'm going to be largely unavailable for the next
couple of weeks or more due to travel. You're far more likely to get
help on the pgsql-general@postgresql.org mailing list than here, as
this really is off-topic for this list.
