Help please. I have 3.1.3 version of Electrum. It won't allow me to send Bitcoin unless I upgrade to version 4.something.  I have my wallet and my password, but sadly, can't find the seed words and that space is grayed out in the wallet menu. I have backed up the wallet by the copy menu item and saved it to a fash drive. But that is the only way I know to back it up.  The problem is that my Mac OS needs to be upgraded because the new version of Electrum won't run on my el Capitan Mac OS. Beofre I begin upgrading and risk incompatibility I'd like advice on the best way to do this.  My prefered solution would be to upgrade to a version of Electrum that will run on El Capitan and allow me to send coins. I want to do that before upgrading my Mac OS. Any suggestions? Thanks!!
