One last question with this Ken. As you may be aware Atik has been releasing new drivers lately that seem to have caused some problems for many users. I had gone back to an old version of the driver that was stable for the EFW2. In looking at the old vs. new drivers carefully, I noticed that Atik switched from the old driver "atikusb.sys" to new driver "libusb.sys" (or something like that). Could switching back to the old driver have caused this mismatched registration state?
I've sent a request to Atik but I think I may just try to uninstall all astro software, including ASCOM 6.2 and reinstall everything to see if that fixes it.
