There currently seems to be an issue with the nova site which is why it fails and also supect when the index files unavailable, I helped a fellow SGP user get the local version up and running yesterday though you do need to get the index files which is the problem.
This contains the index files 4107 to 4119 which covers most common fov.
Will need to copy them to the \usr\share\astronomy\data folder, on Win7/8/8.1 this would be located in the folder.
C:\Users<replace with your USERNAME>\AppData\Local\cygwin_ansvr\
To speed up solving you can remove the index files that are not used, run a blind solve and check the log, located here
Look for a section at the bottom similar to this
log-odds ratio 200.643 (1.37508e+87), 36 match, 3 conflict, 107 distractors, 40 index.
RA,Dec = (189.981,-11.6179), pixel scale 4.27355 arcsec/pix.
Field 1: solved with index index-4107.fits.
Field 1 solved: writing to file ./stars.solved to indicate this.
Field center: (RA,Dec) = (190, -11.62) deg.
Field center: (RA H:M:S, Dec D:M:S) = (12:39:55.693, -11:37:09.182).
Field size: 85.5537 x 57.0552 arcminutes
And you will see which index file solved your image, in this case 4107, go back to the data the folder and remove all but that one, I save them somewhere else in case I need to put any back.
If all that too confusing and you have teamviewer I am more than happy to jump on and help out, provided we can find a mutually acceptable time - PM me if interested.
