[Help] Virtualbox gives error at login

[Burner1977]

Hello everybody,

I have just bought a F4-424 max with TOS6 (6.0.770 and BIOS 5.26). I have the problem that when I install Virualbox and start it, I will go to the login page and try to login with the default admin/admin credentials it gives me an error:
Exception Object
(
[message:protected] => Error logging in to vboxwebsrv.
[string:Exception:private] =>

[line:protected] => 134
[trace:Exception:private] => Array
(
)

[previous:Exception:private] =>
)

When I open the VBoxSVC.log I also see an error:
