I started getting these today. Unfortunately neither restarting nor reinstalling helped. I also so there are plenty of older Jaikoz Crash issues here in the forum, but sadly the solutions are not accessible anymore (links are dead). Please help, screenshot see attached.
Does the Jaikoz main window come up, if so please run Advanced:Create Support Files
If it doesnt even start then deleting the settings.jai file usually resolves the issue
Go to Home : Library : Preferences : Jaikoz
Go to C:\Users\username\Jaikoz
Go to $HOME/.jaikoz/Prefs
Thanks again Paul!!!
