Unable to update AIJ. Continuously see error "the update server ... may be down".

[karenacollins]

Unfortunately there was a bug introduced a while back that prevents the AIJ update feature from working properly. If you continuously see an error that starts with "Network Error!" and contains the phrase "the update server ... may be down", you may have happened to download the problematic update version before we realized it and fixed it. There are two approaches to correct the problem that are one time fixes. In either approach, you will not lose your general preference settings (but see note about memory settings in #2):

1) Download Astronomy_.jar from here:
https://www.astro.louisville.edu/software/astroimagej/updates

Then replace the file of the same name in your AIJ installation folder's "plugins" subfolder.
Then run the update feature and select "daily build" and the update process should work again.

2) Reinstall AIJ 3.2.0 from here:
https://www.astro.louisville.edu/software/astroimagej/installation_packages

You will need to set up your memory allocation again if you use this approach.
Then update to the "daily build".
