Has anyone had any problem using Mikro-Smooth?

Has anyone had any problems using Mikro-Smooth (Mapleshade) on some SACD's and rendering them unplayable? I use Mikro-Smooth and then follow it up with Optrix! No problems with Optrix, but Mikro-Smooth sometimes causes the SACD to be unplayable even after following up with Optrix. Not on all, but some. Any help out there fellow Audiophiles?
