There is something wrong with my gateway 3ds

Today i upgraded my console with my gateway 3ds into emunand 8.1 system.I got my card here:http://www.r4igold3ds.co.uk/gateway-3ds-c-17.html.However when i would like to play games,it noted that there is an error occured.It doesn't help after I change the sd card.What's going on there?

Uhhhh, don't have the Gateway3DS inserted when doing the exploit. Once the Gateway loading screen is up, and has the options, you then insert the Gateway3DS.Yeah, retarded since it didn't used to be that way...
