Please help me! ;(

Have you rebooted the host?
What has changed since the last time the guest worked?

I tried to reboot and it still is coming up with an error and the guest can't be booted up because not even the control panel comes up after the error pops up. After the error pops up the program doesnt even show up after...

And my second question? What has changed since you last used the guest?
Files moved, updates, that kind of thing.

Well not really but last time I used one of my virtual machines I think it installed some windows updates if thats what you mean.....

Try re-installing VirtualBox and when asked select repair and see if that fixes you issue.

So I go on Installed programs on control panel and instead of uninstall click repair right?

yes maybe.

Why not just run the VirtualBox install again?

ill try to repair because I tried to re install and it didn't work.
thank you

It sounds like a corrupted .vbox file to me, in which case reinstalling or repairing the VBox program files folder will do nothing.

Make sure VirtualBox is fully shut down. Maybe even reboot the host to be sure. If you look in the VM folder you should find two files called <vmname>.vbox and <vmname>.vbox-prev. Delete the former and rename the latter (carefully) to the former. Then try it out.

Deleting the file did the trick.

rm ~/.VirtualBox/VirtualBox.xml

Can someone please help i'm in real need of this program i've tried everything can you give me in better detail and exact names of the files i've to deleted and where is VM ??!!

This post is years old and the OP did not even reply back to tell his solution. So don't wake up the deads...
