I have a file that will not play its automation timeline. I have 'nan' in the tempo box and when I hit play the playback wiper disappears. Also there is a meaningless number 36870911 in the bars/beats box. AM was midi synced to my DAW to chase it but I've disconnected all midi sync and turned it off since the problem appeared but no difference.
I've tried restarting and no difference. My default file is fine however.
Can someone help?
