I got my DS-X about a week ago, and it was working absolutely perfectly. The apps menu used to take about 2 minutes to load, which I was somewhat surprised by, buty it wasn't a big deal. But all of the sudden, the next time I booted up my DS-X, it takes 10 minutes for the apps to load (Yes, 10 minutes). I didn't change any games or anything. Anybody else have this problem? Do I format it??
