I am guessing that you are now running Y2K in the READ mode for the LARGE
size.  The snippet of output you show is the tail end of an IMHEADER which
indicates that a UV data file was successfully read.  The "FILE MISSING"
message indicates just that - an attempt to find another file which is
not there.  I really have no idea where you are in Y2K and so am only
able to make guesses as to the problem.  One thing to debug this would
be to try
INPUTS IMHEADER; IMHEADER
since "FILE MISSING" is a common error message from IMHEADER.  Perhaps
you did not FTP all of the files for Y2K LARGE and have not read them
all in.  The Y2K test requires that you download and read in all of the
files, or at least all of the files used for those steps of Y2K that you
invoke.
