The link you provide only show, the part of Armory. But I also need the part of Electrum to use that code of Armory.
The second half of my post explained how do it.
Here's the guide which describes how to import your keys. As OmegaStarScream has already mentioned, you should create a new wallet in Electrum, save the mnemonic phrase (12 words) and send you coins there. This will ensure that you won't have any problems with recovering your coins in the future.
