@ChipMixer: Please disregard the PM I sent you, importing the private keys worked just fine after reading o_e_l_e_o's post above. Smartass that I am I didn't click on the "Import to Electrum" button but directly copy / pasted the private key from the "Withdraw" page. Also of course I didn't read the note about Electrum requiring a special prefix. Maybe put that part in bold? Not sure. Either way I didn't realize there was new information on that page, blinded by routine I guess.
