Free HyperV Performance Monitor Tool and Free Hyper V Configuration Tool crashes on Windows 8 when trying to connect

Hi,

I have Hyper-v core installed on a server and I'm managing it remotely with Win8.
I have installed Free HyperV Performance Monitor Tool and Free Hyper V Configuration Tool on the remote Win8 macine and I can run it the first time.
But as soon as I fill in the values IP/Host username and password, it crashes when it starts to make the connection.
I've tried both with hostname and ip-address.

I always get a window with "... has stopped working."

Extra info: The windows 8 machine is actually a vm running in virtualbox on my mac.

Anyone know why this is happening.
I don't understand why it's crashing. Hyper-v Manager works fine on Windows 8 so the connection between this machine and the server is good.

Thanks.
