Error downloading clover to make a boot USB with Bootdisk Utility

I'm following this link:

​

I get to the part where you configure the clover install and the screens are different. The sample screen shot has a local zip, so I got a zip (Clover_v2.4k_r4813), and put that into the same sub as the Bootdisk Utility, but it doesn't see it.

​

When I format the USB drive, it gives an HTTP error, so I download the .zip, but it doesn't seem to see it.

​

I'm trying to create a bootable USB with Clover on it so that I can access a hackintosh drive.

EDIT: the exact message: Error sending the HTTP request to the server
