Cannot open a session on VM since 4.0.4 upgrade

[Celia Leber]

Ever since I upgraded to 4.0.4 earlier today, I have been getting the following error message:

Failed to open a session for the virtual machine Windows Vista. Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE). Unknown error creating VM (VERR_SUPLIB_WORLD_WRITABLE).

Here is the log:

I tried going into Disk Utility on my Mac and repairing permissions, then rebooting, as suggested on the Forum, but that has not helped. This is a huge problem for me as I rely on using Virtual Box to access some Windows programs on my mac.. Please advise. Thanks!!

I'm really sorry!! I didn't see the part about not pasting log files.. Here is my message without the log. If I messed something up at your end, I'm sorry!
