Which platform is this on, and do you have any important work in the app?
The issue is a combination of SQLite database corruption (very old driver that doesn’t have a newer version in this framework), and random permission revocations on Apple devices. So depending on the device, certain folders need to be removed, or the app reinstalled, but I need to know your exact device to give you the right workaround.
DO NOT reinstall the mobile app if you have work in the app that isn’t synced to the cloud. Apple and Google remove all local app data when you uninstall the app. Other steps are needed.
Please do the following steps slowly and carefully in order to get Apple to recognize a new set of work folders.
Solution 1 of 2:
1.) Sign out of Shot Designer. Then Quit.
2.) Go to Finder → Go menu → Go To Folder → ~/Library/Application Support/
3.) Delete us.hollywoodcamerawork.shotdesigner, and restart the app. Go to the website and reset all your activations, then sign in again. This will not affect your data.
Solution 2 of 2:
1.) Quit Shot Designer.
2.) Move Documents->Shot Designer Scenes to the desktop.
3.) Start Shot Designer. Quit it again.
4.) Copy the *contents* of the folder you copied to the desktop into the newly recreated Documents->Shot Designer Scenes folder.
Please double-check your exact steps in solution 1. The user folder has a Library folder, and this is the wrong one. You have to follow the exact steps to open the system Library folder.
