Troubleshooting After launching NEPTUNE.EXE or SETUP.EXE, I get a 'file missing' error message Your ZIP archive might be corrupted. Solution: try launching SETUP once more. If the problem persists, you will have to download another DEMO version or contact the author for another REGISTERED version. It does not seem to be possible to LOAD, SAVE or PRINT anything! This is normal in the DEMO Version. Nothing seems to happen when 'T-T Pos' or 'T-T Neg' buttons are selected This frequent phoenomenon derives from the fact that only very tight aspects orbits are considered (as their influence in the analysis of Transits is notoriously low). I don't know anything about Astrology! This problem can be more or less easily solved reading some good books about the subject. But caution needs to be taken in their choice because not many of them are really good. An example of good Author is Lisa Morpurgo.
