You are so right, thank you for the link. The Private Key needed to be uncompressed, and in fact Electrum recognized it; however the problem is the HD wallet does not support Sweeping so I'll have to create a non-HD Standard wallet to complete the procedure.
Thanks for the tip! Keep up the good path!
HD wallets should be able to sweep as that should just be moving the coins to your current wallet. You can't directly import the address unless you have a non-HD wallet, but you should be able to sweep regardless.
