Hey, I've been trying to download a lot of games but they won't work. It always says something like it has to make a sav and when he's done it says this: the save data could not be accessed. Please turn the power off and reinsert the DS Game Card. Now what do i have to do? I did see that some people had the same problem and they sad to rename it .nds and .sav but that is already there by me. And something about having woods or not but what does that mean?
