Microstation CONNECT Trial - Failed when starting

Hi all

I've downloaded Microstation Trial (ms100600102en_updt6.exe), installed it.

But when I start it, it stops with a gray screen. No error message.

when trying to connect with Connection Client, I get the message "Not associated with an organization". But I have an account (just me, no organization, since I am testing it).

Hardware: Microsoft Surface Book 2

Any help appreciated
