Help on Event 4x46 Cause: The CPU has requested a memory reset due to a problem in the load memory. To correct or avoid errors: If the memory reset request is repeated after acknowledgment, remove the memory card. If the memory reset request is still not cleared after it has been acknowledged, the CPU must be sent to the manufacturer for repair. I hope this helps, hdhosseini
