What OS that you have used in installing the Electrum? I presume that the OS you've used isn't suitable with the Electrum and make sure you are on the official download website of Electrum, (
https://electrum.org/#download) IIRC if that is your issue.
There are too many wallets that you can choose but Electrum for me is still the best wallet that has unique features. Try to reinstall again and make sure the node is connected to the network. Electrum is very easy to use.
