Windows 8 - can't connect to remote desktop

[yjidszpv]

Hello,
I have Virtual Box Machine, where I've configured remote desktop on port 3390. I've connected to this machine and successfully installed Windows 8 - Enterprise Trial. So far everything has worked excellent.
Then I've installed Guest addition, now, after restart virtual box and windows 8 works without problems, but when I connect to remote desktop(connection successful) I see only black color in remote desktop application window.

I don't remember version number, but I've upgraded virtual box and everything related(I think it was extension pack) today, before windows installation. What can I do with this?
