[issue] Crashes on creating new VM

[Supuhstar]

tl;dr Every time I try to create a new virtual machine, VirtualBox crashes at the end of the process.

I'm using a Surface Pro 2 (512GB) with Windows 8.1 and its latest updates all installed. On it, I have VirtualBox 4.3.10 r93012 (64-bit).

Here's my process:

1. Open VirtualBox
2. Click "New" in the top-left
3. Name and choose the OS type
4. Select the amount of RAM
5. Name and create a virtual hard drive, and select its size
6. Windows reports that VirtualBox has crashed and sends a report
7. Re-starting VirtualBox, noting that the OS is not in the list of OSs
8. Inspect C:\Users\%USERNAME%\VirtualBox VMs\OS NAME HERE\, finding a virtual hard drive and .vbox file
9. Double-click the .vbox file, it then opens VirtualBox and shows the OS in the list
10. Try to run it and it asks me for an ISO
11. Browse for and select the ISO
12. A VirtualBox error dialog pops up, saying the following:
    

    Unable to insert the virtual optical disk C:\path\to\disk.iso into the machine OS NAME HERE.
    
    Argument aControllerName is empty or an invalid pointer.
    
    Details
    
    Result Code: E_INVALIDARG (0x80070057)
    Component: SessionMachine
    Interface: IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

13. I can't start the virtual machine from here...
