I'm rechecking the addresses now, I probably did make a mistake bc I entered them manually. I had them generated at bitaddress.org. I was able to place a successful multi sig order with them but I had copy and pasted them for that. Give me a sec and I'll do the same here
Since you used bitaddress.org you can just simply go to the "wallet details" tab on bitaddress.org and paste the private key that you have. Then copy that other private key and import into your wallet and spend it.
