Background
I'm completely new to bitcoin. I was given the old Armory website to download my "wallet". They said it is super easy, to just download it, create a "receive bitcoins" address and they would send me my coins, which i paid for via paypal.

Well, of course nothing was working. It was offline and through research I discovered I needed to download the Bitcoin Core, And I did not have the latest version of Armory installed.

I checked BitcoinWhoswho and my address/coins are showing up. I just need to get them now.

I have my Keys which are in this format:

xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx
xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx

I also kept a paper copy of it and have the Address where my coin is.

I discovered also that i did NOT need a full node system like Armory. That something like Electrum would be better for a new person.

I installed Electrum but it does not except my keys. Not sure why.

Meanwhile I am still downloading the Bitcoin Core and it's only around 70% done after 2 days.

Question

Is there another wallet, besides electrum that I can download that will except my armory keys and which does not require this multi-day full node download? If so, do I have to wait for the full download on Armory before I can transfer them to the new wallet, since I had already set up Armory as the original receiving wallet?

thanks,
