Vbox 4.3.2 error 0x80000003 on restoring snapshot

[homedoc]

Hi there, I am having a problem restoring from a snapshot. When I try to restore to the snapshot immediately precedent to the following entry in the snapshot tree
"Current State (changed)", I get the following error:
---------------------------------------------------------------------
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0xec287125
Click on OK to terminate the program.
----------------------------------------------------------------------
When I click on ok, another box appears which says:
---------------------------------------------------------------------
Failed to open a session for the virtual machine <VM name>
No error info.
>Details {There is a button that says "Copy"}
---------------------------------------------------------------------
When I click on Copy, here are the copied contents:
---------------------------------------------------------------------
Result Code: RPC_S_SERVER_UNAVAILABLE 0x800706BA (0x800706BA)
Component: ProgressProxy
Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}
---------------------------------------------------------------------

There are two other prior entries in the snapshot tree and they can be restored without a problem. The only difference between the current state and the snapshot producing the error is that the program QuickBooks is started for the first time.

How can I fix this? Many thanks for your help!

I don't know of any way to fix it. Data fragility is inherent in the concept of snapshots.

The best you can do is do a full VM clone from any selected state, and thereby free the cloned VM from snapshot issues.
