AceKard2i?

I have had an AceKard for a while, but now it just doesn't work. I put it in my DS it says nothing is inserted in the game slot. When I put it in my DSi it does the same exact thing. I rubbed with a tissue and it worked, but when I try that again it doesn't work! Please help me!

Here's what works for me:

1. If it doesn't show up in the main menu, turn off the DS.
2. Pop out the cartridge.
3. Pop it back in.
4. Turn it back on.
5. It should show up. If it doesn't, make sure other games still work in your DS.

Tape some paper on the back of the card (over the sticker) to make it thicker, this will make sure the contacts touch. If you swap it in and out a lot, the slot and contacts will slowly wear away, so you need to make sure they're touching. A bit of electrical tape might work, as well, but it doesn't slide as nicely.
