Micro SD (on M3 Simply) problem

Hello to all who care to read this. I have this 2GB Micro SD (Kingston) card for the M3 Simply.Whenever i try to put a folder to store things or to put MP3 to listen on the Moonshell, i get the same problem. When i turn on the M3 and go to the folder, it is recognized as a . exe file instead of a folder! and when i take out the M3 and check it on the computer it's still a .exe file. And besides that, when i delete a folder (doesn't matter if it was changed to .exe or not) it comes back.Is there anything i can do to solve this? Thanks in advance

1) Make sure the M3 simply is updated to 1.07
2) reformat your 2GB card to Fat32/Fat16 (not quick format)
3) drag something like mario kart ds.nds to the root and try running it.
4) if it doesn't work, try a different memory card (brand/size) make sure its NOT a SDHC microsd card. (I use Sandisk)
5) if problem is still the same with other memory cards, you have a faulty M3 simply.
