Could you please post your CCTM run script?
Your error message suggests that you did not specify the LUFRA_CRO environment variable in your run script to point to the relevant MCIP output file so the code will look for land use fractions in the GRID_CRO_2D file, but that you also used an MCIP version that is new enough to store the land use fractions in the LUFRAC_CRO rather than the GRID_CRO_2D file.
Please also note that your post does not seem to be related to the topic of this existing thread. For future posts covering a new topic, please open a new thread and follow the forum posting guidelines.
