Postgress on Windows XP

Hey all, I am having alot of trouble restoring a pg_dump from an old linux machine onto a newer version of postgres on a windows xp machine. Now I tried to use the user interface to restore a .sql file and it will not allow me to restore. Should I try the command line? If not is there a way I could load all the tables and information into SQL Server 2005 then somehow convert it to a format that Postgres will not have any trouble with? Please let me know. If I could get it to run in SQL server should I even bother using postgres like would the code be the same for the program that I have running to add and remove things?
