[SOLVED]melda vst3 plugins disappeared

…the free bundle and a bought 6-band saturation plug . Plugin manager refuses to scan the vst3 version of them ,
vst2 is working .Anybody else ? Btw , where is the list of plugins "not allowed " ?
win 8.1 64bit cubase pro 8

SOLVED : You have to reinstall the vst3 plugs in the cubase pro 8 vst3 folder .

Yeah, I’m only seeing a little small box and not the plugin?
