Downloaded wallet, but saved private key doesn't work

Hi! I’ve downloaded the wallet onto my Mac desktop, but when I try to import my key by entering my private key it doesn’t allow me continue. The private key begins with 5 so I don’t understand where I’ve gone wrong. Can anyone help to resolve this?

I’ve just noticed that the Private Key is only 40 characters long. Is it possible to reset with new keys and begin again?

Yeah it seems like you’re missing part of your key if it’s only 40 characters long :thinking:

Where are you getting the key from, another wallet or did you have it saved someplace from a while ago?

For an existing account - you can only change the keys on the account if you have the keys to the account itself.
