I'm trying the new 2.5.1 (2.5.1.0 and today the 2.5.1.14) version of your fantastic software, but I have a problem with the Plate Solving.
I use Astronometry.net o ANSVR local server and both solve the image, but SGP doesn't get the coordinates and it gives as resolution RA 0.0.0 and Dec 0.0.0..
The log of ANSVR give these information:
[2016-05-21 14:55:34] JOBS/cal: jstr: {"epoch":"J2000","parity":1,"pixscale":1.4
7163497135046,"radius":0,"ra":202.474532736,"orientation":-81.9531390695324,"dec
":47.2027530312}
My system is a little netbook Asus 1005HA with Windows XP. I haven't any problem with older version.
