Hello.
I got a problem with login to your site.
At the beginning it was unable to find my e-mail (aka login). Some time past I successfully logged in to your site, but when I was trying to download some files (like studio or smth.) It threw me back to the login page and I couldn't even enter my credentials, because of continuous page refresh in endless loop.
I can see this problem on Windows10 with firefox 74 (64-bit).
