Hitting "Submit & Compare" now produces "Results rejected as invalid" every time. I ran Novabench a few weeks ago from this machine with no problem; results are on my account. Not sure what changed in the meantime, except that I added more memory?! (Not sure how that could affect upload. . .) I also reinstalled a newly downloaded Novabench but same results. iMac 11,3 running 10.11.6. Will attach sample files. 161223_16GB_test4.nbr 161223_16GB_test1.nbr Oops, I just made earlier iMac i7 results "anonymous" so may no longer be on my account.
