MMM 2016premium is slow, when i uninstall the program there came a message about that is missing Audiovis.dll. Can this be the cause of the problem :-)
This issue has been reported several times in the forum. As yet there is no definitive answer why some users are experiencing this slowdown, however the Audiovis.dll missing does provide a further clue as to what the issue may be.
