Please upload namelist.wps file from WRF and run.mcip.csh file from MCIP for check. However, the error message does indicate that the grid dimension setting is incorrect. Make sure you read the user manual and benchmark.

Is there some reason you are using a version of MCIP that is nearly 7 years old?
MCIP is now included within the CMAQ repository, so it is easy to ensure it is up to date with the version of CMAQ you are using.

As for the error you are seeing, I suspect the problem is that X0, XCOLS, Y0, YCOLS, and BTRIM are set such that either the x- or y-dimension exceeds the available number of grid cells in the WRF output. I believe it is the case that if you set BTRIM = 0, then X0, XCOLS, Y0, and YCOLS are ignored and you get MCIP outputs of maximal extent.
