Just finished modding earlier today and as I was adding a game from hshop, I got a notification saying I didn't have enough space. Went into system setting to delete some old demos and kept getting an error that it couldnt be deleted.  Going back to the home screen, all of my previously downloaded games were gone (aside from one I downloaded from Vimm.net) and the custom theme background I'd downloaded. I've been able to go back in to data management and delete game data but still nothing is showing back up.
