Hacking Cannot load retail games

[Sigma305]

Hey guys, so yesterday I bought MH4U cartridge based and I was playing fine in classic mode, everything worked fine I even played online, but now today, My 3ds wont read the game even after inserting it various times, it wont even read any other games. But when I go to sysnand it does! And when I booted up gateway mode it reads my gateway, any solutions?
