Thanks very much that got rid of the first 2 error messages I was seeing. However, now when VirtualBox tries to restore my session it gets almost all the way to the end (of the blue progress bar) and then shows the error below. What shall I do now?
Failed to open a session for the virtual machine Windows Pro 8.1 dynamic.
Unsupported version 6 of data unit 'hda' (instance #0, pass 0xffffffff) (VERR_SSM_UNSUPPORTED_DATA_UNIT_VERSION).

Re: Failed to open a session for the virtual machine
I split your message from the thread "Kernel driver not installed (rc=-1908)". You can't keep on discussing all of your problems in the same thread. It would end up a huge pile of incoherent messages that bear no match to the thread's title.
The message says that you cannot restore your saved state. You have two options:
The message says that you cannot restore your saved state. You have two options:
- Downgrade VirtualBox to the version that you saved the VM state. Do you remember which one it was? Then you restore the VM and shut it down. You can then re-upgrade VirtualBox to its current version.
- Press the "Discard" state button. You will lose whatever was in memory at the time you saved the VM state. Similar to losing power to your desktop (with no UPS).

Thanks for splitting my message.
If I press 'discard saved state' (under Machine at the top menu right? Command-j?) I won't have to re-create my Virtual Machine? Please confirm, thanks.

Re: Failed to open a session for the virtual machine
I thought that I made it clear that the only thing you're going to lose is whatever you had in-memory at the time you saved the VM state. But to confirm, no, you won't lose your VM.

Re: Failed to open a session for the virtual machine
That worked! Wanted to make sure I was selecting the correct button as well. Thanks for walking me through this.
