When I clicked [Options] I found there was no card listed, so I followed the instructions to activate the card by inserting the card into its reader and plugging it into a USB port and then clicking [Activate new card] and this screen pops up

I do have both the 6 digit card serial number and the 8 digit activation code written down, however, the activation code input box is greyed out; I cannot click in it to input the code. I am assuming that it is looking somewhere on my computer for that code, but I have no idea where that might be. Has anyone here run into this problem before and been able to fix it and restore their X2 to working order again?
PS: When the card is plugged into the camera and I take a few pictures I cannot see the card (Eye-Fi Card 63dfa7) listed in my wifi router WLAN devices but it does appear on my android and I can connect to it with the activation code, so the card must be transmitting.
