I was using the plugins over the weekend. When I went to do a mastering session yesterday three of the Fab Filter Plugins were simply not there. It was easy enough to reinstall them but wondering why they disappeared? Also one of my favorite plugins the VST Stereo Tool was all of a sudden not authorized. No changes to the computer and no one else had used it. Anyone else have this problem or know why it may have happened? Thanks in advance.
