HELP!! VB won't start anymore

[howcome]

Today i felt brave enough to upgrade the VB version on my macboox, running 10.7.2 osx lion.
That was the stupidest thing I could do, because it does not start up anymore. I have tried several installations, over and over again with the same result:

The error message says:
Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).

Resultaat code:
NS_ERROR_FAILURE (0x80004005)
Component:
Console
Interface:
IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

I have been searching for a solution but could not find a suitable one. Any ideas on how to solve it?

Thanx.

From what I read here you need to run the Repair Disk Permissions using DIsk Utility on your MAC host then it should work.
