Yes I have, any way to fix this?This can also happen if you have downgraded a system title. I.e browser for spider hacks etc
You installed Bluecardfix.cia didn't you? Use a spoofed DS Whitelist with the version # maxed out instead.
Spoofed DS Whitelist? Is the DS Whitelist included in the thread with all the updates at you-know-where the one you're talking about? If a new 3DS update comes up, do I have to install an updated spoofed whitelist?
