I added too many threads to the settings in the advanced section of the preferences

I added 4000 threads or something and now toon boom storyboard pro crashes when I start it up. I need to change that setting but I can’t if I can’t even get into the program.

Re-installing may not work as the info is stored in the user preferences. You can remove your user preferences which should restore everything to default.

[user]/Library/Preferences/Toon Boom Animation/Toon Boom Storyboard [Pro]

[C:\Users[username]\AppData\Roaming\Toon Boom Animation\Toon Boom Storyboard [Pro]\

If it were me I would contact Support. They might have a solution. Otherwise I would just move the project files to a safe place and reinstall the software.
