I just created an account, and created my first project. I am unable to do anything else. I can't change or set any setting anywhere without the error: "There was an error trying to complete the current operation. Please contact AppVeyor Support."

The first thing I want to do is set some environment variables for the project. But when that didn't work I tried other settings, and absolutely everything I try to do causes that error.

I see someone else had this problem in December, but I don't see any resolution to it.
