I have this problem. I haven’t tried VSTTransit before. I can login to MySteinberg no problem. But with VSTTransit I just get “Start Login…” in the bottom field. I am running v1.5.22.56 through Cubase 10 Pro on Win10 Version 1909 (Build 18363.720). I have no special characters in my password, just numbers and upper/lower case letter.
