virtualbox.org

I am using VirtualBox version - 4.3.20 r96997
Running Windows 7 Pro 32-bit

When I attempt to start VM, I receive a popup message with the abort button:

NtWriteVirtualMemory/Peb failed: 0xc0000022 (RC=-1073741790)

I then recieve another popup "failed to open a session for the virtual machine "XXXX" ....

The error code is as follows:

Result Code:
E_FAIL (0x80004005)
Component:
Machine
Interface: IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

In the startup log, here are what seem to be some relevant details

Anyone have a suggestion?
