upgrade from 3.1.2 to 3.1.4 breaks all VirtualBox adapters

[Erwin Van Onderbergen]

After upgrading vb 3.1.2 to 3.1.4 i lost all my virtualbox network-adapters after ending setup you end up with a unknow device in the network section of device manager. if you start vb you don't have a host-only adapter and if you try to create it's ending with message "Failed to create the host-only network adapter".i try to install it normal and as administrator but no luck. un-installing and installing version 3.1.2 does also not work anymore i can't create network adapters. i remove a real adapter on my system and install it again and this works good. if i try to manually install the driver for the unknown device i can pick the wright driver from the list but on install it fails with message "not enough system resources to proceed" ( translated from dutch ). i have a very detailed log from the install. is there a workaround to fix this ? i can't run any version of vb anymore. host os is windows seven hp

greetings Erwin
