I could not sort out hot to get this information to Tech Support, so I thought I would post it here. I have several NCH programs and they all work well. I downloaded SoundTap last night and installed it. on reboot, the computer repeatedly threw the STDRIVERX64.sys error with a page fault and I could not get it to boot after ~15 attempts. I did a safe boot and uninstalled SoundTap and it worked fine. I don't know if this is a common bug, but thought I would provide the info to you. Please contact me if you would like any additional information.
