The other day on the EShop I bought Monster Hunter 4 Ultimate to play with my friend, and whenever I try to launch it, the screen goes dark and the it says "An error has occurred. Hold down the POWER Button to turn off the power, then turn it on and try again. I've done this more times than I can count, and still nothing happens. I've searched online for an answer , I've tried the Nintendo 3DS download repair tool (it said that no errors were found but I proceeded anyways and all it did was update the game, which did nothing). I've tried calling Nintendo, and although the customer service was good, they could only narrow it down to two possible solutions: repair or format. I don't want to lose all the data on my 3DS, so formatting isn't an option for me. It would be pointless to get rid of all my data from my other games just to play one game, so I decided not to format. As for the repair, I can't afford the $80 it costs, and I don't think it's anything wrong with the system, as all other downloaded games, apps, and game cartridges work just fine.
I considered the possibility that my SD card couldn't write quickly enough, but the speed is 10 so I figured that this wasn't an issue. I've tried uninstalling and reinstalling the game (painstakingly) but the error message still kept on showing up.
I've been a longtime fan of Nintendo's; I've enjoyed their games since my dad bought me a Gameboy to play Pokemon Yellow and I've been loyal since, but I've run out of options here and I really can't afford to pay the $80 for repair, please help.
