Hey guys, i trashed preferences and things seem stable again PHEW (I hope) still curious to see what is causing these crashes, how does this suddenly start happening??

also, none of my Cubase contained VST presets are loading up, Massive and Serum specifically and msot importantly, which file in preferences holds these?
