I am using an Orion Atlas Pro mount and starry night pro 6.3 on a Toshiba laptop with Windows 7. I have connected my laptop through the Atlas hand controller using the Serial to USB cabling provided by Orion. The software connects to my mount and I am able to slew to various objects using the starry night pro software. The two problems that I have with the software are that I am unable to utilize the park feature or the nudge buttons to move the mount. When I push the park or set up park buttons I get an error message and the software disconnects from the mount. Also, when I try to use the nudge buttons the mount does not respond at all. I am hoping for some suggestions to resolve these two issues.
