Virtual Machines crash on startup

[daltonv]

Hello,
I have a few VMs in my virtualbox right now, and all of the sudden none of them work. They will start up normally, and after about 10-15 seconds, it crashes, and it says "Aborted" next to the VM I was trying to run. This happens on all 5 of the guest OS's, including Windows XP and Ubuntu. It seems to be a problem with the virtualbox software itself rather than the guest OS because one of them prompted to boot into safe mode, and it crashed while I was still selecting an option. Any idea why this might be happening?

Well, as I was trying to find the log file, I clicked on "session information" and some message popped up and said something like "Invalid memory address. Could not write." And now, everything works fine. Strange.

Well, it's happening again, so I guess I shouldn't trust it fixing itself magically. I've attached a .zip of the log files for my Ubuntu VM, hopefully someone will be able to help.
