I just started getting the Deep Architecture message. I'm working on a new project in LP 9.1.8 In my case the message pops up when I'm playing a part on the keyboard, I don't even have to be recording it, just playing. I haven't got the message when I'm playing back a track. Its seems like its a response to a midi overload. StrangeNo, I'm on 9.1.7, (not 8 due to plugin issues), song is new, just happened out of the blue. I have got round it by opening the last backup, which is ok... the message "Deep Architecture! Unpack some folders" seems absurd.
