During installation process I cannot login using my existing Atlassian Account (which works when I login on the website).

After I entered my email and password the blue login button changes and shows a loading symbol (rotating wheel) but nothing happens. I cannot proceed and install/use the software. 

I tried a few times (yesterday and today) with different versions (2.3.1.0 and 2.1.2.5 and 2.3.5-beta-0).
