Ok deleting the db made the application much more manageable now, I can at least play music without interruption.
However, there still seems to be a communication error between MM and my external hd. Which I've never had.
Upon launch of MM, I still get the original SQL database error from the first post of this thread. It happens when I try to edit the ID3 details, as well. Most annoying is the sync from my external library is not saved within MM, so every time I launch MM, the program has to rescan my entire library as if it were new. But these were always issues from the beginning.
Even the desktop shortcut icon is now broken.
