This looks like a bug in the error recovery code. Very strange since you are the first to report such a problem.

The ROUND OFF (0.40625) > 0.40 "error" is not a problem. This is normal when testing near the limits of an FFT range. The SUM(INPUTS) != SUM(OUTPUTS) seems to be a bug.

Can you email the pNNNNNNN file to me for debugging?

To work around the problem, try this: Exit mprime. Add the line "CpuSupportsSSE2=0" to local.ini. Run mprime until you get past the loop. Exit mprime. Remove the local.ini line. Restart mprime.
