I can get only the initial entry screen, where some basic terms are stated and your two choices are to buttons labeled "Enter" or "Leave." When I hit Enter, nothing happens at all.

I am able to get in and log in using Firefox.

Update: I have two different "Chrome profiles" (I created one accidentally and never use it). But I tried the UMD on the profile I don't use, and doing that, I can at least get to a login screen for the UMD, but it then tells me my username/password combo is wrong. Meanwhile, that same username/password combo works fine to get me into the UMD on Firefox. I can even get onto the UMD via Chrome on my phone, using that same username/password combo. Meanwhile, on my main Chrome profile, i can't even get to the UMD login screen. Very strange!
