I have looked at Gary Hawkins' posts, but the responses there do not seem to solve my issue.
I am running AIJ Version 5.3.2.
When I click on the multi-aperture tool from the main menu, I get the following error message:

AIJ 5.3.2.00; ImageJ 1.54h2; Java 18.0.2 [64-bit]; Mac OS X 12.7.1; 22MB of 12288MB (<1%)

I tried to downgrade to an older version of AIJ that I know was working, and this is the message I get:

Network Error! Check your internet connection. If good, the update server at the University of Louisville may be down. In that case, try the update at a later time.

My network is up, so I'm wondering if the update server is indeed down. ?

Thanks for any help you can provide.
