This decodes to: "Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above." Memory referenced: 0x00000000 IRQL: 0xff Read/write: Write (1) Address which referenced memory: 0x828B7220 http://msdn.microsoft.com/en-us/library/ff560129%28v=VS.85%29.aspx Looks like a NULL pointer reference or maybe a deliberate "we should never get here" failure.
