you downloaded the wallet from here: electrum.org?
if no you have installed the wrong wallet.
if yes: whats the color of the dot in the right corner? nor green i think.
Worst part is that I sent btc to it and it has therefore not received them.
what you can do it install an other wallet. use the seed from electrum and use with the new wallet.
or export the private keys and use them in an other wallet.
i dont know which wallet works. but you can google it.
