Hi there,

Dealing with error messages isn't the outcome I'd like for you to have. It's essential you have a seamless experience while using the program. Rest assured, I'll be glad to guide you towards getting a resolution. 

Based on the error you've described, I suspect you may be experiencing browser-related issues that can cause issues such as the one you've described above. Clearing cache and cookies helps with fixing most browser issues. You can do this by following the steps in this article: Clear Cache and Cookies. To confirm, do you get the same error when you enter a date range that's shorter? I suspect that the date range may be broad to the point that it affects the report from being displayed correctly. 

Feel free to let me know what happens. I'll be here to help.
