KISS is Keep It Simple Simon.
Many of these cards have trouble with spaces or other than alphanumerics in name, passwords and folders. I've seen it fail on upper case letters too.
I'm not saying that's it but as you bump into these things you learn more KISS.
I've just bought a WFT-E4 wireless transmitter for my Canon 5d Mk II camera. I'm setting up my wireless, however when I try and enter my login info in the FTP settings section to try and browse for a target folder for my photos, it says:
Could not connect to the destination server.
Invalid login name or password.
Does anybody know why this is? The login information is correct!
Thank you for any help!
