Hello there, everyone. Alex Poter, a member of the customer service team, here. A 'QuickBooks script error' has piqued the interest of some Quickbooks users. Several important documents have missing. When loading a file, efforts were made to attach a user account that wasn't existing at the time. The application couldn't find the account you were trying to access. Under rare situations, it's conceivable that you're attempting to establish an account that already exists.
