When trying to install SourceTree 126.96.36.199, in third step "Atlassian account", on log in screen, I'm getting "Oops, you've made a malformed request." message. Don't know what happend. It seems, that my account is working, althrough I've never get "e-mail verification" e-mail, but I did get "reset password" e mail. I've tried on to mails, email@example.com and firstname.lastname@example.org , same issue. I've tried to check in Windows Firewall, nothing there. I can't use "Log in with Google" button, nothing happend when pressed. Tried to use random account name, getting same message. I've event tried to delete cookies, uninstall browser extensions(Google Chrome), tried to use different-older SourceTree (188.8.131.52 and some older one, don't remember), same issue.
Don't have firewall, anti-virus software etc. I can't even attach file in png and bmp formats!
