Hello, I download RW (Read_Write Utility v1.7) to my Windows 10 OS. When I run PCI window, after trying to check a few PCIe ports, now it always opens an error window, saying: "Access violation at address 00000000004B7BFF in module 'Rw.exe'. Read of address FFFFFFFF836956D8" I cannot open 'PCI' window anymore now. Even I shutdown the computer, power on again, this error window always comes back. I don't see any history file in the Rw.exe folder to remember what it continues to do for a new relaunch. Can you help me out? Best Regards, Robert
