If you know the IP address of the Apex you can program it using the classic dashboard. ?In your browser you can use this link (change it to your Apex Jr IP address). ?192.168.1.1/nstatus.sht
On the Neptune Apex forum someone had a similar problem. ?They called Neptune's support and they sent him a firmware that would reset the apex back to factory defaults. ?He was then able to access via classic dashboard using the default id and password.https://forum.neptunesystems.com/showthread.php?4803-Password-Reset
I just got done swapping around some of my units and re-configuring them last night. I have three APEX systems and can let you borrow on of the screens if you need to. I will just use Fusion for feeding time. I think I am a little far from you though, but PM me if interested and we'll work something out.
