My Analogue Factory does not make a sound when opened in Mainstage 2.2.2

[speminalium8]

And additionally stops all other plug-ins from making any sound. (Btw, I use Mainstage in 32 bit mode as I use Kontakt4.) I have to remove the AF plug in and close Mainstage 2 and then re-open without the AF plug in before I can then use the sounds from the other plug-ins
