I also added blocks for Maine. http://www.electionsciencefoundation.com/temp_images/maine_blocks.zip
There are "island" blocks which are completely surrounded by other blocks. It is probably worth scanning for them and designating them part of the block that they are enclosed by. Unless they have a population greater than a district, it is not possible for them to be placed in a different district to their "parent" block. ---- Election-Methods mailing list - see http://electorama.com/em for list info
