Aaaahhhh...good tip rbescape. I had tried the deletion of myconfig.cs several times without success, but your suggestion re: an old script motivated me to take the time to go back through the scripts I use. I discovered one that must have a default setting that deactivates the pack when jetting, now my shield pack stays on.
I am soOOooo embarrassed to be so stupid.
Thank you sir/maam for the tip, and thanks to everyone who tried to help me.
