Can't Create a new Document

[AdobeIsKillingMe9]

When I try to create a new document it gives the message "An unknown error has occurred."  Followed by "Can't create a new illustration. The command was cancelled."  Why is this happening?  How am i supposed to start a project?

When you ask a question you need to provide some basic information

-Forum quick start https://forums.adobe.com/docs/DOC-5601

Mac or Windows, and EXACTLY which version of the operating system?

Recent Mac AND Windows operating systems have been known to cause "odd" problems

Are you using a computer Administrator account with full read/write permission?

Exactly which version of the program do you have that is causing problems?

Start with this option:

Delete Illustrator Preferences:

Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (macOS) as you start Illustrator.

You are prompted to delete the current settings.
