Hi Themos, Sorry for not getting back quicker on the v1.03 error O enocuntered. I started ppa.py in Anaconda console as suggested and got this: The system cannot find the path specified. C:\Users\Steve\Anaconda>cd C:\Users\Steve\Documents\PhotoPolarAlign C:\Users\Steve\Documents\PhotoPolarAlign>ppa.py Traceback (most recent call last): File "C:\Users\Steve\Documents\PhotoPolarAlign\PPA.py", line 1501, in <module> APP = PhotoPolarAlign(master=ROOT) File "C:\Users\Steve\Documents\PhotoPolarAlign\PPA.py", line 1495, in __init__ self.Sniff_AstroTortilla() File "C:\Users\Steve\Documents\PhotoPolarAlign\PPA.py", line 1305, in Sniff_AstroTortilla lfn = os.listdir(dir) WindowsError: [Error 3] The system cannot find the path specified: 'C:\\Users\\Steve\\AppData\\Local\\astrotortilla.sf.net\\AstroTortilla/*.*' Not having dabbled in Python before I can't see if there is a new config setting I'm missing to enable/disable local solving. I'm using Win 7 pro as OS and don't have Astrotortilla installed - but do have Astroart5 Hope that's a genuine bug I found for you and not me doing something stupid!
