unfortunately I didnt know that Eyefi Cards are no longer supported. I bought one from Ebay because I want to use my old 450D for the Wifibooth. However, I cant get the activation key.
The original EyeFi app doesnt work anymore and Keenai doesnt create an upload key. Is there a way to use it, or did I buy crap?

I really hope I can find the key because I'd rather like to use Wifibooth than Shuttersnitch for the Booth.
Thanks a lot for your help.
