As to glib.  That is going to be a core package in most linux installs.  You probably have it, but it's out of date.  You could always rectify that and run feather... but that's a topic for another forum.  Chances are a. will solve that problem (assuming a debian based linux, could need a "pacman -Syu" or some other command for other distros)

If the balance IS zero, AND this wallet used to have Monero.  Then you should be able to see the the last transaction.

As I asked before what does the transactions tab show?  Is it empty?  I think you suggested that before.

If so, I am starting to wonder if you have the right wallet open.
