Glad you joined. It will be good to fly with you again. Hopefully on the same side!
I think you've done the Mods install correctly. I assume you have unzipped the BA7 Modpack V2017.03.19.zip file to your mods folder.
Ignore the install screenshots - they have not been updated.
In JSGME, the only mod you need to activate is BA7 Modpack V2017.03.19 - It seems to be all the required mods compiled into one.
The true test is: Can you successfully join the BA7Test1 (Mods On) server?
