I'm assuming you are using electrum rather than electrum HD.
Start your old electrum wallet, then click "file" in its menu, then select "new/restore". Click the OK button in the popup box that opens, then follow the instructions below.
An install wizard window should open. At the top of it select the "Restore a wallet or import keys" option, then click the "next" button.
Another window will open with a box in it that you can type your private key(s) into.
After that click the "next" button and another series of windows should open. Leave each window's settings as they are and click the "next" button in each one until the wallet opens.
You can leave the password boxes blank, the electrum wallet can work without a password.
When the wallet opens it should sync within minutes and show your Bitcoins. You can use it to send them wherever you like.
Thank you so much, that worked perfectly!
And thank you to all that replied, I was about to pull my hair out over this
