My electrum version is 3.1.3, and the bottom left window says synchronizing, but never changes.
I will install latest version and let you know how it goes.
The latest is Electrum-3.3.8
Once you install the latest one, I am pretty sure you will see your coins are there.
There are nothing to worry anymore.
Good luck
Edit:
Many thanks for the help.
You are most welcome. I was a bit late to make this post LOL
