mjcaiken Many have reported these problems. Like you, ASIair worked great for a few years, but last several updates have been filled with problems. In my case plate solving problems and complete failure to guide after a meridian flip. I'm not sure why the software has gone rotten after years of good, reliable service.
I hate to but am considering other options. I can't understand how software is released (twice) where meridian flips don't work. It's a pretty basic requirement for astro software. Does anyone test the software?
Hopefully, they will straighten it out before customers start to leave. A reputation is a terrible thing to waste.
