If you don't require the transaction log for recovery purposes then you need to change the recovery model that the database is using to SIMPLE so this doesn't happen again. You can do this by executing
ALTER DATABASE databasename SET RECOVERY SIMPLEDBCC SHRINKFILE should then be able to reduce the log file to a reasonable size. Alternatively you can clear the transaction log of committed transactions by executing
BACKUP LOG databasename WITH TRUNCATE_ONLYDBCC SHRINKFILE should now also be more effective, however if you don't change the recovery model to SIMPLE the log file will just fill up over time again. Search on "Selecting a Recovery Model" in SQL Server Books online for more information.
