Alright, so I played Brain Age on my R4 with a SanDisk 1.0GB. Got bored of it, simply deleted it with the MicroSD plugged into the USB thing on my computer. Now, Brain Age won't go away. It's stuck as a file with no size. Everytime I refresh view the card, it just pops back up there, a "corrupted" file with 0KB. Any way to get rid of it?
