This has been happening since at least Saturday, and others have reported this as well (in the regular Hypervisor forums).

Neither the “manually download” nor the “Download Manager” links do anything.

I’ve tried 6 different computers (Windows XP and Windows 7 Home and Windows 7 Enterprise), 4 different web browsers (IE10, IE11, Firefox, chrome), and 3 different ISP (Verizon FIOS, Road Runner, and whoever supplies our Corporate LAN–AT&T or something).

I’m not sure VMware is even aware that there’s an issue.
