Ok i just recently updated my 1gb Microsd to a SanDisk 2gb microsd that I bought on black friday for 20bucks at best buy. Ok so I transferred my files to the new 2gb micro, and seemed to work perfectly, until I tried changing a skin for the DS. So I added the skin and some music to the 2gb Micros, then I turned on my DS and saw that the skin that showed up was the stock skin that first came with Simply M3. So I tried changing it to the skin i just added and it didn't show up at all! my other skins were there but not the one I inputted. Then I changed the skin to one of my existing skins and turned off the DS and turned it on again and it reverted back to the stock skin, not the skin I left off with. Then on top of that i tried running the moonshell program and then it just stop in the middle of loading the program. So I plugged in my 2gb back into the computer and tried deleting some files, and it worked on the computer. But then as soon as I load my 2gb into the DS, those files that i deleted from the computer still appear and seems like it was never deleted. So i tried formating the 2gb using fat16 and fat32 and nothing, it says it formatted the disk but, when i plug it into the simplyM3, it still has all the files that were there prior to formatting the drive. Does anyone know what to do? I am getting relatively frustrated and I don't know what to do. Can anyone help me out?
