Can't launch virtualbox-ose-4.1.14

[Quentin SCHWERKOLT]

I'm unable to launch VirtualBox-ose 4.1.14 on FreeBSD 9.0-RELEASE and FreeBSD 9-STABLE.

I try install it with ports and pkg_add and when I launch VirtualBox, an
 error window appear witch said: "Failed to create the VirtualBox COM 
object. The application will now terminate.", and the detail is 
"Callee RC:
NS_ERROR_ABORT (0x80004004)" and a core dump is generated.
Cordially, Q. Schwerkolt
