Restoring Snapshot crashes VBox Manager

[Agux]

Host operating system is Windows 7 64 bits, AMD FX 8 cores, 32gb ram. Guest os is Windows 7 64 bits as well, 4 cores, 8gb ram. I'm saving a snapshot of the guest OS so I can restore it at a later time. When restoring the state later, it throws an error: Oracle Virtual Box Manager has stopped working. When debugging the exception on Visual Studio, the error message that causes the crash is: "Unhandled exception at 0x6982841b in VirtualBox.exe: 0xC0000005: Access violation reading location 0x0000000000002fb0."

This is the information that appears on the dialog box when the VBox manager crashes:

Problem signature:

Problem Event Name: APPCRASH Application Name: VirtualBox.exe Application Version: 4.1.16.0 Application Timestamp: 4fbb8645 Fault Module Name: atio6axx.dll Fault Module Version: 6.14.10.10243 Fault Module Timestamp: 4ca2a0cf Exception Code: c0000005 Exception Offset: 00000000007f841b OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Additional Information 1: 723a Additional Information 2: 723ab4b3dad23d8f58acf49fd9fe84b8 Additional Information 3: 87a3 Additional Information 4: 87a32e5c5b29686d9f7ea7b10e24bb3c

I have repeated the process many many times expecting a different outcome, but it happens everytime, the state is saved but upon retrieving it crashes.
