Regarding your seed words there are two possibilities:

- One is that the seed was generated in an old version of electrum. Electrum pre 2.0 used a different wordlist that does include "shiny" in it. You can find those words here: https://github.com/spesmilo/electrum/blob/3.2.2/lib/old_mnemonic.py#L30

- The other possibility is that you made a mistake writing down the seed words. You can refer to the seed words by going to wallet menu > seed. You can also fix any spelling mistakes by consulting the dictionary for current versions of electrum here: https://github.com/spesmilo/electrum/blob/3.2.2/lib/wordlist/english.txt . So instead of shiny try shine.

Finally I'd like to point out that electrum never ever generates bip39 seeds so what third space is saying cannot be true. Current versions of Electrum do use the bip39 dictionary though but a different method of converting the mnemonic to the wallet's private keys.
