error reading grm file

I had the following error messages when running a model with QTL effect
treated as random. I suplied loki.grm file for ASREML to read and was
prepared according to the manual. What might be the possible cause? I
copied part of the loki.grm from line 295 till 310 to give the idea what
are on the those lines as ASREML pointed line 300 on the message.

part of loki.grm
