[SOLVED] Error writing virtualbox.xml

[litbea]

After installed 3.0.6 version, every time I try to set up general parameters, or set up a new machine, a "could not save the settings file....VirtualBox.xml ...VERR_ACCESS_DENIED".
I've tried to allow everybody account to write and access the file and the folder, but nothing seems to work.
Any solution?
Thanx!

Did you reboot the Host yet?

If the problem persists I would reinstall VirtualBox.

I didn't reboot, it wasn't told. But after some minutes (I left the PC and came back later, about 1,5 hour) the problem was gone.
Seems like something related with the installation not finished... sure a reboot is the first thing to do!
