Hello
I have been using virtualbox for a long time and it ahs always worked well. Now, today, when I try to launch it I get the following error:
"
Failed to create the VirtualBox COM object.

The application will now terminate.



Start tag expected, '<' not found.

Location: 'C:\Users\Jack/.VirtualBox\VirtualBox.xml', line 1 (0), column 1.

D:\tinderbox\win-4.1\src\VBox\Main\src-server\VirtualBoxImpl.cpp[485] (VirtualBox::init).

Result Code: E_FAIL (0x80004005)
Component: VirtualBox
Interface: IVirtualBox {c28be65f-1a8f-43b4-81f1-eb60cb516e66}
"
What should I do? Please help. I am running Windows 7 32-bit as a host. Please help me.
thank you

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.

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

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
