Please,if you want people to help you should give some more details.
-From where did you download your "old" Electrum wallet?
-Can you show us a screenshot of the "upgrade" window popping when you try to spend your coins?
What can I do apart from report it?
Look if the coins are still in the address where you deposited your coins using an explorer,if you've been scammed, they won't be there (moved by the hacker) or give us the address so we can check it.
