Problem with a second .grm file

Hello:
 
My problem is that ASReml cannot read a second .grm file (associated with dominance effect). The message is in the output bellow. There is no problem with the file since it is read when I define it as the A matrix (associated with the pedigree). The file is equivalent to a matrix of 1535 x 1535 (see ASReml code bellow). When the file has fewer dimensions it is read without problem (791 x 791). Thanks.
