If you don't need transaction log backups (in most cases of a simple, local databases you don't), just set your database to simple recovery model. Then use the Enterprise Manager to shrink the logfile. You may need to do it more than once to get it to the desired size (usualy 10-20 MB should be enough for a database of this size).
