Just like TBC, we in the federal government (maybe there are others), never get an email back from this site.
This site requires you to enter an email, and it never arrives (not even in spam, junk). This is the same problem with TBC. At least with TBC, the construction site for downloading TBC does work - all the time. I haven't found a way to download current version of TRW.
Please provide one - this is, I think affecting all federal computers in US.
