UltraVNC Single Click Creator Confusion

I was trying to create a single click executable using the online creator.  I followed the instructions to create my own version and tried to upload it to the online creator; but I kept getting an "unable to validate userid" error.  Despite all convention.  It turns out that when the online creator page says foo is username and foobar is the password, they mean it literally.  This would have been easier to troubleshoot if the forum post entitled "Common mistakes with creator tool" had mentioned that.  It helpfully states that the files must be in the root of the zip file and that the bmp files are limited to 256 colors, but nothing about the username and password using the common placeholders of foo and foobar.  Only until I did some further searching did I find another thread that enlightened me.  In my head scratching I came to understand that this tool was made by non english speakers, but I have also dealt with enough non english speakers to know that foo and foobar are used universally as they are here.
