Thanks for checking in. I was running into the invalid package error as I went to Admin → Developer Tools → Module Loader. There were no logs on screen other than generic text that I had uploaded an Invalid Package. However, we did end up getting a SugarChimp up and running with the aid of a third-party contractor—I'm sure I'll be able to get the fix from him soon.
For now, we can close out this ticket. We'll be revisiting purchasing a license once our evaluation is over.
