Usage of COPY FROM STDIN in postgres

I just started using Postgres and I'm trying to create a sample db to understand its functions, looking around, I found some scripts in pgfoundry.org.
I understand the commands, since I previously used both Oracle and MS-SQL, but all the scripts I'm running return errors when they reach the "COPY FROM" instruction. More precisely, the error is thrown at the first element that should be inserted in the given table.

I've tried running the scripts both as queries and as pgScripts, but in both ways I'm getting an error at the first row after the COPY FROM.

I'm using pgAdminIII and I used StackBuilder to install PostgreSQL 9.2.4.1 as a DB Driver. May I be missing some basic configuration that's preventing me from running this command, or I just did not understand they way it works?

EDIT:

The error is:

ERROR:  syntax error at or near "7"

where the text is:

COPY action_abilitations (id, group_action_id, partecipation_role_id, group_id, created_at, updated_at) FROM stdin;
7   4   13  37  2012-03-10 16:41:43.797787  2012-03-10 16:41:43.797787`

pgScript is a local script extension of pgAdmin, which you most probably do not want here.

pgAdmin is a GUI, not a console application - there is no stdin you could easily use. If you need stdin to stream your content, use psql, which is a console application - with the \copy meta-command of psql.

If you have a file (which you obviously do), just use SQL COPY from pgAdmin:

COPY action_abilitations (id, group_action_id, ...)
FROM 'C:\Users\usernexus\Desktop\database05-12-2012.sql';

The file needs to be readable to the postgres system user.
