ERROR: relation “name” does not exist

I am trying to import a postgresql database table sent to me in phpPgAdmin, I am following the instruction from this import database

But after doing so, several error appear, I also tried to import the database using cmd but the same error continues to persist

DROP TABLE
postgresql.sql:33: ERROR: relation "accessories_id_seq" does not exist
postgresql.sql:34: ERROR: relation "public.accessories" does not exist
BEGIN
postgresql.sql:40: ERROR: relation "public.accessories" does not exist
LINE 1: INSERT INTO "public"."accessories" VALUES ('1', 'Vario V8', ...
^
postgresql.sql:41: ERROR: current transaction is aborted, commands ignored until end of transaction block

I researched the problem here in stackoverflow but people who had the same error are making new database tables and and thus most of the errors comes from mixed-case spelling, I’m just pulling data from a database sent to me.
Any answers would be greatly appreciated.

In cmd I used this command

"%PROGRAMFILES%/Postgresql/9.3/bin/psql.exe" -v ON_ERROR_STOP=1 -U postgres -d postgres -a -f C:/Sites/xmastool/postgresql.sql 

The file is an SQL file

After removing all the drop statements this error now appears

postgresql.sql:33: ERROR: syntax error at or near ""
LINE 1: /*
^
postgresql.sql:34: ERROR: relation "public.accessories" does not exist
BEGIN
postgresql.sql:40: ERROR: relation "public.accessories" does not exist
LINE 1: INSERT INTO "public"."accessories" VALUES ('1', 'Vario V8', ...
^

This is the first lines of the code
