Your problem is not the upgrade from VirtualBox 4.1.x to 4.2.4 but rather the missing shared folder mapping. This case is not correctly handled by VirtualBox when a saved state is restored. The workaround is to create a dummy folder on the host (see your log file) with the missing folder path to make VBox happy when it tries to restore the folder mapping.

Thank you.

As I suspect this might be a common error where a shared path disappears I would suggest the following improvements:

a) Tell the user this, vs giving cryptic message. b) Give the user the option to continue to launch vm and automatically remove path.

There are cases, where it would not be possible to recreate the folder or path temporarily and or the user does not want to turn off or cannot turn off the vm to change this share.

Thanks for you feedback. VM is up and running.
