Error message: "No outer planet ephemeris for date?"

a. This error message occurs when entering a chart date using an incorrect format or if the date is outside the ephemeris date range.
Enter dates in month, day, year format, each separated by a space or period or comma but NOT a hyphen. The year must be a 4-digit year like 1947, not 47.

b. This error message occurs when starting the program.
When this happens, it means that Chartwheels has lost the path to the ephemeris files. To fix it, you must reconstruct the NVPATH.DAT file.
To reconstruct the NVPATH.DAT file : At the C:\CH2 prompt type:

COPY CON:NVPATH.DAT <Enter>

<Ctrl> Z (hold down Ctrl key and hit Z at same time)
Finally hit <Enter>.

You'll see message: 1 file copied.
Start up Chartwheels. You should now be able to go to the Main Menu. If necessary (i.e., if chart files are not in the C:\CH2 directory) select the File Path for Charts option in the Main Menu to reset the chart file path to the directory on your system where you're reading chart files from.
