Amplitube missing model message disappeared

[panenutella]

Hello everyone, first time posting here so I hope this is the right section. I just would like to know how to re-enable the "missing model" message. I've missclicekd the window "Don't show again this message" and now i don't know anymore which models i'm missing from the Slash presets I bought. I've tryed to look everywhere and even reinstalling everything, but that message doesn't pop up anymore. Thank you!
